Question

A farmer sells 7.1 kilograms of pears and apples at the farmer's market. 4 5 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?

Answer 1

She sold 2.6 kilograms

Answer 2

2.6Kg

Explanation:

Let the weight of apples be x and that of pears be y.

The farmer sold 7.1 kg of apples and pears.

4.5 of the 7.1kg is apples

That’s

`x + y = 7.1kg`

`4.5kg + y = 7.1kg`

Subtract 4.5kg from both sides

`4.5kg - 4.5kg + y = 7.1kg - 4.5kg`

`y = 2.6 kg`

The farmer sold 2.6kg of pears at the market.
