The ratio of red cars to blue cars in a parking lot was 8 : 7. If there were 48 red cars, how many blue cars were there?

1 answer:

8 0

What you need to do is multiply both sides by the same number. If 8 times 6 is 48, then 7 times 6 is your answer.

Answer:

F) 63

Step-by-step explanation:

Find the original total stories 10 + 8 + 16 + 8 = 42.

Original ratio of Mary's stories to total stories is 8/42 or 4/21.

Then form equation 4/21 = 12/x ; multiply both sides of 4/21 by 3.

4/21 = 12/63

The students need to write 63 stories to keep the ratio of Mary's stories to total stories the same.
