When wheat is milled, 80% flour is obtained. How much flour will be obtained from 440 kg of wheat?

It is known from the condition that when wheat is milled, 80% of flour is obtained. You need to find how much flour will be obtained from 440 kg of wheat. To do this, we will compose and solve the proportion.

Let us denote by the variable x the weight of flour obtained after grinding 440 kg of wheat.

Let’s designate 100% as 440 kg of wheat.

So, let’s write down the proportion:

440 kg – 100%;

x kg – 80%.

440 / x = 100/80.

We are looking for an unknown average term of the proportion, for this, the product of the extreme terms is divided by the known average term of the proportion.

x = (440 * 80) / 100 = 35200/100 = 352 kg flour
