Using these results, we can set up some ratios to help us find out the predicted number of each colored chip. so we can find out how many chips have been picked in total by adding 12 + 18 = 30.
12/30 chips are pink
18/30 chips are blue
Now we need to set these equal to a total of 100 chips.
To do this we will need to simplify the two ratios.
12/30 --> 6/15 ---> 2/5
18/30 --> 9/15 ---> 3/5
Now we take the simplified fractions and set them equal to 100 chips.
2 *20 40
-- = -- There are about 40 pink chips
5 *20 100
3 *20 60
-- = --- There are about 60 blue chips
5 *20 100
