Question

40 cattle can graze a grassland for 60 days. The number of cattle that will graze a grassland 2 times as large in 40 days is:

Answer 1

Answer:

≅ 53 cattle

Step-by-step explanation:

We can solve this problem by making the question simple.

First, let us solve for the cattle that can graze the same grassland in 40 days.

Then we can double the cattle to find out the number that can graze on the grassland 2 times as large.

We know that;

40 cattle can graze a grassland                 -- in 60 days

? How many cattle can graze the same grassland  -- in 40 days

Cross multiplication:

The cattle that can graze the same grassland in 40 days = (40 x 40)/60

                                                       = 26.66 (say, because cattle cannot be in decimal points)

The number of cattle that can graze the grassland 2 times as large = 2 x 26.66 ≅ 53 cattle
