Four fully solved problems that show the exact reasoning students need for each worksheet type. Use these as a model before assigning practice.
Problem
2/3 = ?/12
Compare the denominators
Ask: what do I multiply 3 by to get 12? Since 12 ÷ 3 = 4, the multiplier is 4.
Apply the same multiplier to the numerator
Multiply the top number by 4: 2 × 4 = 8.
Verify by simplifying
Divide 8/12 by the common factor 4: 8 ÷ 4 = 2 and 12 ÷ 4 = 3, giving back 2/3. ✓
Problem
4/5 = 12/?
Compare the numerators
Ask: what do I multiply 4 by to get 12? Since 12 ÷ 4 = 3, the multiplier is 3.
Apply the same multiplier to the denominator
Multiply the bottom number by 3: 5 × 3 = 15.
Verify
Divide both parts by 3: 12 ÷ 3 = 4 and 15 ÷ 3 = 5, giving back 4/5. ✓
Problem
Is 6/8 equivalent to 9/12?
Cross-multiply one way
Multiply the first numerator by the second denominator: 6 × 12 = 72.
Cross-multiply the other way
Multiply the second numerator by the first denominator: 8 × 9 = 72.
Compare the products
Both products equal 72, so the fractions are equivalent.
Problem
Simplify 18/24
Find the greatest common factor (GCF)
Factors of 18: 1, 2, 3, 6, 9, 18. Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24. The GCF is 6.
Divide both parts by the GCF
18 ÷ 6 = 3 and 24 ÷ 6 = 4.
Check that the result is in lowest terms
3 and 4 share no common factor besides 1, so 3/4 is the simplest equivalent.
Four misconceptions we see most often when grading 3rd–6th-grade work, with the correct reasoning teachers can use to re-teach.
Incorrect
2/3 = 4/5
Correct
2/3 = 4/6
Equivalent fractions are made by multiplying (or dividing) both parts by the same number — not by adding. Adding 2 to both 2 and 3 changes the ratio, so 4/5 names a different amount than 2/3. Multiplying both parts by 2 gives 4/6, which keeps the same ratio.
Incorrect
1/2 = 2/2
Correct
1/2 = 2/4
If you double the top number, you also have to double the bottom number. Changing just one part creates a brand-new fraction with a different value — 2/2 equals 1, not 1/2.
Incorrect
3/5 = 9/10
Correct
3/5 = 9/15
Here the top was multiplied by 3 but the bottom was only multiplied by 2, so the ratio changed. The rule is: whatever you do to the top, you must do to the bottom — multiplying both by 3 gives 9/15.
Incorrect
6/8 is wrong; the answer is 3/4.
Correct
6/8 and 3/4 are equivalent fractions — both are correct.
A fraction and its simplest form name the same amount. 6/8 isn't an error — it's just not in lowest terms. Mark it wrong only when the problem specifically asks for the answer in simplest form.
