Question

45 cows Can graze a field in 15 days. How many cows will graze the same field on 9 days​

Answer 1

Step-by-step explanation:

let x number of cows will be needed

no.of cows = 45 ,no.of cows=x

no.of days= 15. ,no.of days =9

here 45 cow graze the field in 15.In 9 days more cows will be needed.So we can say that they are inversely proportional.

45* 15 =x*9

675 = x * 9

675/9 = x

75 =x

therefore 75 cows will graze the same field.
