4th grade fraction word problems worksheets

Fraction word problems for fourth grade run three story types: adding and subtracting fractions with the same denominator, multiplying a fraction by a whole number, and finding a fraction of a set, like 3/4 of 20 stickers. Answers can simplify, like 5/10 becoming 1/2, and a sum can pass one whole, like 1 1/6, per 4.NF.B.3 and 4.NF.B.4.

The kind of problems you'll get

Read each story. Show your reasoning and include the unit in each answer.

  1. Zoe uses one ribbon piece 1/4 yard long and another 1/4 yard long for a theater costume. What is the combined length in yards?

    Answer: 1/2

  2. A board for a birdhouse is 3/4 foot long before 1/2 foot is trimmed away. How many feet of the board remain?

    Answer: 1/4

  3. Caleb cuts 22 equal ribbon pieces for an awards display, each 1/2 yard long. What is their total length in yards?

    Answer: 11

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

Every version prints on US Letter or A4, with its answer key after the problems.

How to teach this

Start each problem with one sorting question: are same-size pieces being put together, or is the story taking a fraction of a group? The first kind keeps its denominator; the second kind starts with division. A quick bar drawn in the work space settles most arguments: eight equal pieces, shade three, shade two more.

Watch for: Kids add the bottoms along with the tops, turning 3/8 + 2/8 into 5/16. The bottom number names the size of the pieces, and same-size pieces keep their name; only the count changes. Kids divide by the top in fraction-of problems, starting 5/6 of 48 with 48 ÷ 5. The bottom says how many equal parts to cut, so divide by it first. Kids stop after the dividing step, so 5/6 of 48 comes back as 8. That's one sixth. The top says to take five of those parts: 8 × 5 = 40.

Common questions about fraction word problems

What kinds of fraction problems are on the fourth grade sheet?
Three kinds, mixed: adding or subtracting fractions with the same denominator, a whole number times a fraction, and finding a fraction of a set. Five problems per sheet, each with room to show work and an answer line.
Will the denominators ever be different?
Not at this grade. Unlike denominators need equivalent fractions, which is fifth grade work. Here every add-or-subtract story uses same-size pieces, so the thinking stays on the story, not on renaming fractions.
