During the lunch rush, the "catch of the day" is ordered 24 times. If the number of "catch of the day" orders represents 2/9 of the total lunch orders x, write an equation that could be used to determine the number of lunch orders taken that day?

For this problem you want to isolate x, which represents the total number of lunches.

so (2/9) x = 24.

then if you want to solve, you would multiply both sides by the reciprocal of 2/9 which is 9/2 because (9/2) (2/9) cancel each other out. so the total lunches would be equal to x = (9/2) (24)

The answer is (2/9) x = 24
