Fraction Worksheets

36 free printable problems — simplifying, unlike-denominator addition, and decimal conversion — with a toggleable answer key.

Tip: print once with answers hidden for students, once shown for the key.

Set 1 — Simplify to Lowest Terms

Divide numerator and denominator by their GCF.

1.40/64 =
2.32/64 =
3.60/72 =
4.13/39 =
5.36/69 =
6.16/78 =
7.27/54 =
8.44/88 =
9.4/40 =
10.24/57 =
11.48/63 =
12.2/22 =

Set 2 — Add & Subtract, Unlike Denominators

Find a common denominator first; give answers in lowest terms (improper form OK).

1.1/10 + 1/2 =
2.1/2 − 2/5 =
3.2/3 + 2/5 =
4.2/3 + 3/8 =
5.2/5 + 3/10 =
6.1/6 + 5/12 =
7.1/2 + 4/5 =
8.2/5 + 1/2 =
9.5/6 + 1/2 =
10.1/3 + 4/6 =
11.4/5 + 1/2 =
12.1/3 + 3/4 =

Set 3 — Convert to Decimals

Divide numerator by denominator; every answer here terminates.

1.19/25 =
2.7/8 =
3.1/5 =
4.2/5 =
5.1/16 =
6.3/5 =
7.3/20 =
8.1/2 =
9.7/20 =
10.7/25 =
11.1/4 =
12.37/40 =

Teaching Notes: Three Skills, One Thread

The sets share a through-line: equivalent fractions. Simplifying (Set 1) moves down the equivalence chain via the GCF; adding with unlike denominators (Set 2) moves up it to a common denominator; converting to decimals (Set 3) is the equivalence between fractional and positional notation. Set 1 hides two near-coprime traps (36/69 and 24/57 — GCF 3, easily missed); Set 2's 1/3 + 4/6 = 1 rewards noticing 4/6 simplifies first. Check tools: GCF calculator for Set 1, fraction-decimal calculator for Set 3 (including why 1/3 repeats but 1/4 doesn’t).

Frequently Asked Questions

What grade levels do these fraction worksheets fit?

Set 1 (simplifying) starts at grade 4; Set 2 (unlike denominators) is the grade 5 core standard; Set 3 (fraction-to-decimal) spans grades 5-6. Together they trace the standard elementary fraction sequence.

Why do some Set 2 answers look 'improper', like 13/10?

Sums above 1 are left as improper fractions because both forms are correct and courses differ on preference. 13/10 = 1 3/10 — accept either, or require the mixed form as an extra conversion step.

Why do all the Set 3 decimals terminate?

Every denominator's prime factorization contains only 2s and 5s (2, 4, 5, 8, 10, 16, 20, 25, 40, 50), which is exactly the condition for a terminating decimal. That makes the set self-checking — a repeating answer means a division error.

How do I print the answer key?

Toggle Show Answer Key and print again — answers appear inline in place of the blank lines, and screen-only controls are hidden on paper automatically.

Where can students check their work?

The fraction to decimal calculator shows the division (including why some decimals repeat), the GCF calculator verifies simplifications, and the long division calculator walks the underlying division steps.
