Question

a bag contains 6 red tiles and 15 yellow tiles. remove 2 red tiles. How many yellow tiles should she remove so that the ratio of red tiles to yellow tiles in the bag stays equivalent to 6:15? show me

Answer 1

would this be the same as if I remove 2 red, than comes back an remove the same amount from the 15 like remove 2 yellow to equal out the same as the first set of tiles?

Answer 2

So we are supposed to remove 2 red from the 6 red, and x yellow from the 15 yellow so that
4/(15-x) = 6/15
60 = 90 - 6x
6x = 30
x = 5

check:
the original ratio was 6/15 = 2/5
the new ratio is (6-2)/(15-5) = 4/10 = 2/5
