The moisture content of freshly cut grass is 60%, and the moisture content of hay is 15%.

The moisture content of freshly cut grass is 60%, and the moisture content of hay is 15%. How much hay can you get from 1.7 tons of freshly cut grass?

Let’s find the percentage of the dry part in freshly cut grass:
100 – 60 = 40%.
Let’s determine the mass of the dry part contained in 1.7 tons of grass:
1.7 * 40/100 = 0.68 t.
We find out how much% is the dry part in the finished hay:
100 – 15 = 85%.
To calculate the mass of hay, we denote it by x and make up the proportion:
0.68 / 85 = x / 100;
x = 0.68 * 100/85 = 0.8 t.
Answer: 1.7 tons of grass will make 0.8 tons of hay.
