the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.
ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!
simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).
the gcf of 48 and 16 is 16.
divide both terms by 16:
48 ÷ 16 = 3
16 ÷ 16 = 1
reducing to simplest form:
48 : 16 = 3 : 1
