Total number of burgers sold by the restaurant with cheese = x
Ratio of the total number of burgers
with cheese to total number of burgers without cheese = 8 :1
Let us assume the common ratio to be = x
then
8x = 64
x = 64/8
= 8
So
The number of burgers sold without cheese = 8 * 1
= 8
Then
The total number of burgers sold by the fast food restaurant = 64 + 8
= 72
So the total number of burgers sold by the fast food restaurant is 72. I hope the procedure is clear enough for you to understand.
