A farmer sells 9.1 kilograms of apples and pears at the farmer's market. 2 5 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?

5.46 kilograms or 6.6 kilograms

Step-by-step explanation:

Assume that 2 5 in your question has two possible meaning:

2/5 of this weight is apples

Let divide 9.1 kilograms into 5 equal part

=> 1 equal part = 9.1 / 5 = 1.82 kilograms

Because 2/5 of this weight is apples, so the weight of apples accounted for 2 equal parts

=> the weight of apples is: 2*1.82 kilograms = 3.64 kilograms

=> the weight of pears is: 9.1 kilograms - 3.64 kilograms = 5.46 kilograms

2.5 kg of this weight is apples

Given the total weight is 9.1 kilograms

=> the weight of pears is: 9.1 kilograms - 2.5 kilograms = 6.6 kilograms
