Solve: 1. A bag contains 6 yellow marbles, 18 purple marbles and 24 black marbles. a) What is the ratio of yellow:purple:black marbles? (in simplest form)

b) what is the ratio of purple marbles to marbles? (in simplest form)

c) if I take out 3 black marbles, add 8 yellow marbles, and add 10 purple marbles, what is now the ratio of yellow to purple to black marbles? (in simplest form).

a= 6:18:24

b= 18:48

c= 14:34:21

a) 6:18:24 = 1:2:4

b) 18:48 = 9:24

c) 14:28:21 = 2:4:3

Step-by-step explanation:

a) make the ratio and find the gcf, which is 6. Divide all the numbers by 6 to simplify it to lowest terms

b) make the ratio and find the gcf, which is 2. Divide both numbers by 2 to simplify to lowest terms.

c) solve for black marbles = 24 - 3 = 21 black marbles

   solve for yellow marbles = 6 + 8 = 14 yellow marbles

   solve for purple marbles = 18 + 10 = 28 purple marbles

Make the ratio and find the gcf, which is 7. Divide all numbers by 7 to simplify to lowest terms

I hope this helped and please mark me as brainliest!
