Question

A fast food restaurant sold 35 burgers with cheese if the ratio sold with cheese compared to without cheese was 7:3 how many burgers did they sell total

Answer 1

A 7 to 3 ratio means that for every time they sell 7 burgers with cheese sold, they also sold 3 burgers without cheese.

So you solve this by figuring out how many times they sold 7 burgers and then you use that number to find your answer.

35 / 7 = 5

So they sold 7 burgers 5 times.
So that means that they also sold 3 burgers 5 times since for every 7 burgers with cheese they sell 3 burgers without cheese.

So 3 * 5 = 15

You then add your two numbers and you have your answer.

35 burgers with cheese + 15 burgers without cheese = 50 burgers total.
