When you see “25 % off” on a pair of trainers or your gaming accuracy listed as 78 %, turning that percentage into a decimal—0.25 or 0.78—gives you the exact numbers you need to work out prices, stats, and scores without the percent sign getting in the way. [Jump to the questions](#practise-now)

## Topic guide

### What this worksheet practises

This worksheet focuses on converting percentages into decimals. This is a very common requirement in compound interest and depreciation questions, where you need a decimal "multiplier" to make the calculation efficient.

### Key method

Percent literally translates to "out of 100". Therefore, any percentage is simply that number divided by 100.

- Take the percentage value and remove the % sign.
- Divide the number by 100.
- To divide by 100 mentally, move the decimal point two places to the left.

### Worked example

**Convert 42% into a decimal.**

Step 1: Remove the % sign to leave 42.

Step 2: Divide by 100 by moving the decimal point (which is currently after the 2) two places to the left.

42 → 4.2 → 0.42

The answer is 0.42.

### Common mistakes to avoid

The most frequent mistake involves single-digit percentages. Converting 5% to 0.5 is a classic error. 0.5 is actually 50%. You must move the decimal point two places, which requires adding a zero: 5% ÷ 100 = 0.05.

### Things to remember

If the percentage is greater than 100%, the decimal will start with a whole number. For instance, a 125% increase means you have 125% of the original, which converts to the decimal multiplier 1.25.
