Question

There are 144 people in an audience. The ratio of adults to children is 3:5. How many adults are there?

Answer 1

`54`

Explanation:

ratio is `3:5` so consider that `8` parts all together
`144/8=18` so each part has `18` people
`3` parts are adults so `3*18=54` of them
and `5` parts are children so `5*18=90` of them
