What this worksheet practises
This worksheet practises sharing an amount into a given ratio. Ratios are used to divide quantities unequally, and are commonly found in problems involving money, recipes, or dividing physical materials.
Key method
The standard method for sharing an amount by a ratio involves finding the value of a single "part".
- Add the numbers in the ratio together to find the total number of parts.
- Divide the total amount by the total number of parts to find the value of one single part.
- Multiply the value of one part by each number in the original ratio to find each person's share.
Worked example
Share £40 in the ratio 3:5.
Step 1: Find the total parts.
3 + 5 = 8 parts
Step 2: Find the value of one part.
£40 ÷ 8 = £5 per part
Step 3: Multiply to find each share.
First share (3 parts): 3 × £5 = £15
Second share (5 parts): 5 × £5 = £25
The shares are £15 and £25.
How to check your answer
To confirm your calculation is correct, simply add your final shares together. In the example above, £15 + £25 = £40, which matches the original total amount being shared.
