Question

Benny went to his local zoo that featured 12 reptile exhibits. If these reptile exhibits make up 60% of the zoo’s exhibits, then how many exhibits does the zoo have in total?

Answer 1

20

Explanation:

question can be rewritten as '12 is 60% of what number'

we can use the proportion: is/of = %/100

is = 12

of = n

60% = 60/100

12/n = 60/100

now cross-multiply:

60n = 1200

n = 1200/60

n = 20
