TreShaun's full marker has enough ink in it to paint three 4 inch by 4 inch squares. If he colors in two 6 inch by 2 inch rectangles, what percentage of ink is left?
How many square inches are in each 4 by 4 square? ** Each 4 by 4 square equals 16 square inches because 4 x 4 = <<4*4=16>>16
How many square inches are in three 4 by 4 squares? ** Three squares equals 48 square inches because 3 x 16 = <<48=48>>48
How many square inches are in each 6 by 2 rectangle? ** Each rectangle uses 12 square inches because 2 x 6 = <<2*6=12>>12
How many square inches are in both 6 by 2 rectangles? ** Both rectangles will use 24 square inches because 2 x 12 = <<2*12=24>>24
How many square inches are left? ** He has 1/2 of the ink left because 24 / 48 = 1/2
What percentage of ink is left? ** He has 50% of the ink left because 1/2 x 100 = <<1/2*100=50>>50
