Now put both together to solve real problems with money and measuring. **Example.** A ribbon costs £3.20. Priya wants 1/4 of it. She divides £3.20 by 4: £3.20 ÷ 4 = £0.80. So 1/4 of £3.20 is £0.80. *(drawing: One of the four equal parts is worth £0.80.)* **Example.** A rope is 2.5 m long. Ben cuts off 0.75 m. Line up the decimal points and subtract: 2.50 − 0.75 = 1.75 m left. **Tip.** To find a fraction of an amount, divide by the bottom number. To subtract decimals, line up the decimal points first. **Recap.** Divide for fractions, line up the points for decimals, and you can solve any money or measuring problem. ## Practice 18 questions on this page, each with its working shown. ## Needs first - [Fractions of amounts (harder)](https://lightmysky.com/learn/mathematics/fractions-of-amounts-harder-mt_3y7xKP9MjU) - [Adding fractions (same denominator)](https://lightmysky.com/learn/mathematics/adding-fractions-same-denominator-mt_CBHwluE6Lp) - [Decimal equivalents of tenths and hundredths](https://lightmysky.com/learn/mathematics/decimal-equivalents-of-tenths-and-hundredths-mt_TqDq6jyOmL) ## Opens up - [Decimals and fractions (age 10+)](https://lightmysky.com/learn/mathematics/decimals-and-fractions-age-10-mt_4K1dr204Hi)
