Question

At a carnival , 7 out of 10 people order a hot dog. If there is 90 people at the carnival, how many of them did

NOT order a hotdog?

Answer 1

27 people

Explanation:

Out of 10 people, 7 people ordered a hot dog.

Multiply both sides by 9:

Out of 90 people,
`7*9` people ordered a hot dog.

Thus, 63 people ordered a hot dog.

Number of people who did not order a hot dog:
`90-63=27`
