Question

In a museum, the ratio of adults to children is 13 to 5. If there are 288 people in the museum, how many children are there?

Answer 1

Answer:

number of children  = 80

Step-by-step explanation:

So, we have a ratio of 13 adults : 5 children

This means that for every  18 ( 13 + 5 )

people in total we have 5 children.

This can be displayed Algebraically as,

288/18 = 5x

where x is the number of children

x = 80

Another way of doing this question is to find what one unit is,

number of adults + number of children = 288

13 x + 5 x = 288

18 x = 288

x = 16

and then multiply by ratio.

number of children =  5 x = 5 ⋅ 16

= 80
