Question

John is ordering 50 t-shirts. 30% of the shirts need to be small, how many shirts need to be small

Answer 1

So 30% of the 50 t-shirts need to be small.

You can just multiply the two together, to get 15 shirts that need to be small.

Long way: 30% = 3/10

1/10 of 50 is 5

1/10 * 3 = 3/10

5 * 3 = 3/10

15 = 3/10
