A fast food restaurant sold 64 burgers with cheese. if the ratio of burgers sold with cheese compared to without cheese was 8:1, how many burgers did they sell total?

64/8=8 they sold 8 burgers w/o cheese. 64+8=72

So,

64 represents 8 units. To find 1 unit, simply divide 64 by 8.

64/8 = 8

Each unit is worth 8 burgers.

There is only 1 unit of burgers without cheese.

The restaurant sold 8 burgers without cheese.

Adding that to the number of burgers they sold with cheese, we have our answer.

8 + 64 = 72

The restaurant sold a total of 72 burgers.
