Wheat makes 80% of the flour. How much wheat was ground if you got 2.4 tons of flour? How much flour will be obtained from 2.5 tons of wheat?

By condition, the part of the number, expressed as a percentage, is known. Find the number itself:
2.4 / 80% = 2.4 / 0.8 = 3 (t).
You can solve it using proportions:
Flour 2.4 tons – 80%
Wheat x t – 100%.
We find the unknown average term of the proportion:
x = 2.4 * 100/80 = 3 (t).
Answer: 3 tons of wheat were ground.
2.
The whole number is known, we find its part, expressed as a percentage:
2.5 * 80% = 2.5 * 0.8 = 2 (t).
Answer: you get 2 tons of flour.
