Okay, since they give you the ratio and its multiple choice, all you have to do is find which numbers that are given as answers, are divisible by 7 and 5. So, which is the answer?

anonymous · Answer

Divisible is a number that is capable of being divided by another number without a remainder: "24 is divisible by 4".

You could not be more correct:) Good job!

$$2(l+b)=96$$
$$l/b=7/5$$------------$$5l=7b$$
solve for a and b
