Question

If the ratio of red hairbands to green hair bands is 5 to 9 with a total of 70 hairbands, how many of them are green?

Answer 1

45

Explanation:

This can be written as 5r:9g. Add 5 and 9 to get the total of 14. You can write a ratio of 9 green: (out of) 14 total = x green: (out of) 70 total. Multiply 9 and 14 by 7 to get 45:70. Therefore, if there are 70 hairbands, 45 are green.
