13. The number of elephants at the circus was two fifths of the number of horses. If there were 16 elephants, how many
horses were there?


Sagot :

We are required to find the number of horses at the circus.

The number of horses in the circus is 40

let

number of horses at the circus = x

number of elephants at the circus = 2/5 of x

= 2/5x

If there were 16 elephants:

number of elephants at the circus = 2/5x

16 = 2/5x

divide both sides by 2/5

16 ÷ 2/5 = x

x = 16 × 5/2

= (16 × 5) / 2

= 80 / 2

x = 40

40

number of horses at the circus = 40
