This Grade 5 medium-1 worksheet builds equivalent ratios by multiplying or dividing both parts of a ratio by the same whole number. Students simplify ratios to lowest terms using greatest common factors and scale recipe quantities up step by step. A matching exercise pairs scaled ratios with their equivalents, helping learners see that 1:2, 2:4, and 4:8 all describe the same comparison relationship between two quantities in different sizes.

Ratios Introduction
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Multiply both parts of 1:2 by 3 to get the equivalent ratio 3:6.
2. An equivalent ratio of 2:5 with first part 6 is 6:15.
3. Simplify 4:6 by dividing both parts by 2 to get 2:3.
4. The ratio 10:15 in simplest form is 2:3.
5. If a recipe uses 2 cups flour to 1 cup sugar, then 4 cups flour needs 2 cups sugar.
6. Multiply 3:4 by 5 to find the equivalent ratio 15:20.
7. Simplify the ratio 12:8 to lowest terms: 3:2.
8. An equivalent ratio of 5:7 with first part 25 is 25:35.
9. If 1:3 is a ratio, doubling both parts gives 2:6.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
1:2 multiplied by 4
→ 4:8
4:8
10:15 simplified
→ 2:3
2:3
3:5 multiplied by 2
→ 6:10
6:10
8:12 simplified
→ 2:3 (from 8:12 divided by 4)
2:3 (from 8:12 divided by 4)
