A farmer sells 7.7 kilograms of apples and pears.3/5 of this weight is apples, and the rest is pears. How many kilograms of pear

kompoz [17]

Answer:

The weight of pears is 3.08 kg

Step-by-step explanation:

A farmer sells 7.7 kilograms of apples and pears.

3/5 of this weight is apples.

This means that the weight of apples is:

3/5 of 7.7

=> $\frac{3}{5} * 7.7 = 4.62kg$

The weight of apples is 4.62 kg.

The weight of pears will therefore be:

$7.7 - 4.62 = 3.08 kg$

The weight of pears is 3.08 kg.
