Question

Roger is planning a picnic, He will invite two times as many boys as girls. If he invites 18 people, how many boys and how many girls will get invitations?

Answer 1

He will invite 6 girls and 12 boys.

Explanation:

Let number of girls be `x`
Then the number of boys will be equal to `2x`

So you have:

`x+2x=18`
`3x=18`
`x=6`

So, he will invite 6 girls and 12 boys.
