A farmer sells 8.3 kg of apples and pears at the farmers market this way is apples and Restless Paris how many kilograms of Pari
Serga [27]

Answer:

She sell <u>2.075 kilograms</u> of pears at the farmer's market.

Step-by-step explanation:

<u><em>There is a mistake in the question some data is missing, so the correct question is below: </em></u>

<em>A farmer sells 8.3 kg of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?</em>

Now, to find the kilograms of pears.

Total weight of apples and pears = 8.3 kg.

Weight of apples = \frac{3}{4} of 8.3 kg.

So, to get the weight of apples:

  \frac{3}{4} \times 8.3

=0.75\times 8.3

=6.225\ kg.

Thus, the weight of apples = 6.225 kg.

Now, to get the weight of pears we subtract the weight of apples from the total weight of apples and pears:

8.3-6.225\\\\=2.075\ kg.

Therefore, she sell 2.075 kilograms of pears at the farmer's market.
