How it works

Print fractions worksheets grade 4 classes can start on tomorrow. Sheet type covers equivalent fractions, comparing unlike fractions, adding and subtracting like denominators, mixed numbers, whole number × fraction, and tenths plus hundredths. The page opens on equivalent fractions. Make a new sheet changes the numbers.

What grade 4 covers

Common Core 4.NF.1 to 4.NF.7 cover equivalent fractions, comparing two unlike fractions and like denominator sums, mixed numbers included. They add a fraction times a whole number, and decimals for tenths and hundredths. A footnote limits denominators to 2, 3, 4, 5, 6, 8, 10, 12 and 100. Texas 4.2(G) and 4.3(A) to 4.3(G) cover similar ground with no denominator list, and leave whole number × fraction to grade 5, in 5.3(I).

The slip to expect

The classic grade 4 error is 2/6 + 3/6 given as 5/12: the pupil adds everything in sight. Print Add like denominators, sums below 1 and say each problem aloud as 2 sixths plus 3 sixths. A quick check: 3/6 alone is 1/2, so 5/12 cannot be right.

  • Order three unlike fractions is a stretch sheet. Both standards texts stop at comparing two fractions in grade 4.
  • On Equivalent fractions: divide down, accept 4/6 for 8/12, since grade 4 is not asked for lowest terms.
  • Print Rename tenths with denominator 100 the day before Tenths plus hundredths, shown in two steps.

Questions and answers

Are these 4th grade math worksheets fractions only?

Yes. Every sheet type on this page is a grade 4 fraction skill, and each prints with its key on page 2 unless you clear Answer key. For the other grade 4 topics, see 4th grade math worksheets.

Why do the denominators stop at 12?

The Common Core grade 4 footnote lists 2, 3, 4, 5, 6, 8, 10, 12 and 100. Every fraction pupils start from uses one of them. An equivalent fraction may land on a larger denominator, such as 3/10 = 15/50. Texas sets no list.

Does grade 4 add fractions with unlike denominators?

Only tenths with hundredths. Common Core 4.NF.5 has pupils rename 3/10 as 30/100 and then add 3/10 + 4/100 = 34/100. Its footnote says unlike denominators in general are not a grade 4 requirement. They arrive in grade 5 in both texts (5.NF.1 and Texas 5.3(H)).

All 18 sheet types

Equivalent fractions 3

  • Equivalent fractions: divide down 8/12 = 4/6 = 2/3. Divide top and bottom by the same number, and again if you can. The key lists every fraction on the way down, because each one is a correct equivalent fraction.
  • Equivalent fractions: multiply up Each problem gives a fraction and a multiplier: for 2/3 and × 4, multiply top and bottom by 4 to get 2/3 = 8/12. The pieces get smaller and more numerous, and the amount stays the same. That is Common Core 4.NF.1 in one line.
  • Missing numerator or missing denominator To turn 3/4 into twelfths, multiply top and bottom by 3: 3/4 = 9/12. Half the problems hide a numerator and half hide a denominator, and no multiplier is given. Some run downward, from 6/10 to fifths.

Comparing unlike fractions 3

  • Compare unlike fractions, any method 5/6 > 3/4, by twelfths (10/12 > 9/12) or by noticing that 5/6 is only 1/6 short of 1. Different numerators and different denominators in every pair, and the pupil chooses the method. About 1 pair in 6 is equal.
  • Compare with a common denominator 2/3 = 8/12 and 3/4 = 9/12, so 2/3 < 3/4. Both fractions are rewritten with one denominator and then the numerators decide. There is ruled space for the two rewritten fractions.
  • Order three unlike fractions 1/2 = 6/12 and 2/3 = 8/12, so 5/12 < 1/2 < 2/3. Three fractions to write from least to greatest. Neither standards text asks grade 4 for more than two at a time, so treat this one as a stretch.

Adding and subtracting like denominators 5

  • Add like denominators, sums below 1 2/8 + 3/8 = 5/8. Eighths plus eighths make eighths: the denominator names the size of the piece and does not change. The first adding sheet of the grade (Common Core 4.NF.3a, Texas 4.3(E)).
  • Add like denominators, sums past 1 5/8 + 6/8 = 11/8 = 1 3/8. The sum passes 1, so the key gives it as a fraction greater than 1 and as a mixed number. Fractions greater than 1 are grade 4 work in both texts: Texas 4.3(A) covers a/b when a > b, and Common Core 4.NF.3b breaks 2 1/8 into eighths.
  • Missing addend, like denominators When a fraction plus 3/8 makes 7/8, the fraction is 7/8 − 3/8 = 4/8 = 1/2. One addend is hidden in each problem, and some totals are 1 whole. The key shows the subtraction that finds it.
  • Subtract from 1 or a whole number 1 − 3/8 = 8/8 − 3/8 = 5/8. The whole is renamed as 8/8 first. Later problems start from 2 or 3, where one whole is renamed and the rest stay put.
  • Subtract like denominators 9/10 − 3/10 = 6/10 = 3/5. Take tenths from tenths. The key shows 6/10 and then 3/5, and whether 6/10 earns full marks is your call.

Breaking apart and mixed numbers 3

  • Add mixed numbers with the same denominator 2 5/8 + 1 6/8 = 3 11/8 = 4 3/8. Add the wholes, add the eighths, then trade 8/8 for another whole. About half the problems need that trade.
  • Mixed numbers and fractions greater than 1, both ways 2 1/8 = 8/8 + 8/8 + 1/8 = 17/8, the example in Common Core 4.NF.3b. Half the problems run this way and half run back, from 17/8 to 2 1/8. Every conversion shows the wholes as 8/8 first, not a rule about multiplying and adding.
  • Subtract mixed numbers with the same denominator 3 1/4 − 1 3/4 = 2 5/4 − 1 3/4 = 1 2/4 = 1 1/2. One whole is opened into 4/4 so there are enough fourths to take away. About half the problems need it.

Multiplying by a whole number 2

  • Multiply a fraction by a whole number 4 × 2/3 = 8/3 = 2 2/3. Multiply the numerator by the whole number and keep the denominator, which is 2/3 + 2/3 + 2/3 + 2/3 written the short way. The key shows the raw product, then lowest terms, then a mixed number when the product passes 1.
  • Rewrite as a multiple of a unit fraction 5/4 = 5 × 1/4, and 3 × 2/5 = 6 × 1/5 = 6/5: the two examples in Common Core 4.NF.4a and 4.NF.4b. Pupils fill in the missing whole number or unit fraction. Texas leaves whole number × fraction to grade 5, in 5.3(I).

Tenths, hundredths and decimals 2

  • Rename tenths with denominator 100 3/10 = 30/100. Multiply top and bottom by 10. This is the one pair of unlike denominators Common Core grade 4 adds (4.NF.5), so the renaming gets a sheet to itself.
  • Tenths plus hundredths, shown in two steps 3/10 + 4/100 = 30/100 + 4/100 = 34/100, the example in Common Core 4.NF.5. There is a blank line for the renamed tenths. Answers stay over 100, ready to be read as a decimal.
