An artist is using three different colors in a mosaic. The ratio of green to blue to yellow color tiles in the mosaic is 4:6:9. She has 42 blue tiles to use. How many green and yellow tiles does she need??
you have 42 blue tiles (6) so 42 / 6 = 7 so since 6 lots of = 42 1 lot of = 7 green has 4 sets of tiles so 4 x 7 = 28 yellow has 9 sets so 9 x 7 = 63 the ratio from green blue yellow is 28:42:63
