Max can make 1 greeting card in 5 minutes. How many greeting cards can he make in 30 minutes?

Answer 1

let's turn this into a rate,

1 greeting card/ 5 minutes

in order to get from 5 minutes to 30 minutes, we need to multiply both sides by 6

6 greeting cards/30 minutes

Answer 2

He can make 6 greeting cards in 30 minutes.

Explanation:

Given,

Max can make 1 greeting card in 5 minutes,

So, we can write,

5 minutes = 1 greeting card,

We have to find the number of cards for 30 minutes,

Multiply 6 on both sides,

30 minutes = 6 greeting cards,

Hence, he can make 6 greeting cards in 30 minutes.
