A local health-food store is making a cereal mix that has nuts to cereal ratio of 2 to 7. If they make 144 oz of the mix, how many ounces of nuts will they need?

Question

2/7 = 144 over the letter x

Answer 1

Just increase the numbers using the same ratio to get the desired total number of 144

For example..... 2/7 = 2/7 * 10/10 = 20/70 but 20 + 70 = 90 not good enough

then 2/7 * 11/11 = 22/77 but 22 + 77 = 99 not good enough

but 2/7*16/16 = 32/112 and 32 + 112 = 144

So, the answer is 32 and 112
