Question

a fast food restaurant sold 35 burgers with cheese if the ratio of burger sold the cheese compared to without cheese with 7 : 3, how many burgers did they sell in total?

Answer 1

let's start with 7:3
35 have cheese so change that to: 35:?

35÷7=5 so 7×5=35
so let's multiply 3×5=15
so the new ratio is 35:15 add those numbers together and you have 50 burgers sold in total.

hope this helps!
