Math application problem [must be answered today! ] 10 kg of grass was sunburned into 3 kg of grass. According to this calculation, how many tons of such vegetables can get 1.5 tons of hay?

X/ 1.5= 10/3

X=5

Quantitative relationship:

Grass 1 weight/hay 1 weight = grass 2 weight/hay 2 weight.

That is, hay ratio = hay ratio

Because the ratio of these two quantities is constant, the weight of grass is directly proportional to the weight of hay.
