there are 5 pink shirts and 9 green shirts. If there are 27 green shirts, how many pink shirts are there?

Step-by-step explanation:

5 pinks = 9 greens

x pinks = 27 greens

Cross multiply

5pinks * 27 greens = x pinks * 9greens

Divide both side by 9green

5 pinks * 27 greens / 9greens = x pinks

Then green cancel greens

x pink = 15 pinks

Then, 27 greens implies 15 pinks

15 because 9/27=3 so 5x3=15
