Question

Corey makes a mosaic from equal sized tiles in ten rows,each with ten tiles.seventy tiles are green and the rest are blue what percent of the tiles are blue tiles

Answer 1

10 times 10 is 100, so there are 100 tiles

70 of them are green. That means 100 - 70 = 30 are blue.

30/100 = 30% are blue
