Question

The Booster Club sells 240 cheeseburgers. 1/4 of the cheeseburgers had pickles, 1/2 of the remaining burgers had onions, and the rest had tomato. How many cheeseburgers had tomato?

Answer 1

Answer:

60 cheeseburgers

Step-by-step explanation:

Find the fraction of cheeseburgers with tomato as 1 - 1/4 - 1/2 = 1/4.

Multiply this fraction by the total: 1/4 * 240 = 60

Answer 2

Answer: 90 cheeseburgers had tomato

Step-by-step explanation:

You know that $\frac{1}{4}$ of the 240 cheeseburgers The Booster Club sold had pickles. Then, the number of cheeseburgers that had pickles was:

$cheeseburgers\ with\ pickles=(240)(\frac{1}{4})=\frac{240}{4}=60$

The number of remaining burgers is:

$240-60=180\ cheeseburgers$

According to the exercise, $\frac{1}{2}$ of the remaining cheeseburgers had onions, and the rest had tomato (which means that $\frac{1}{2}$ had tomato).

Therefore, you can multiply the remaining burgers by $\frac{1}{2}$  in order to calculate the number of cheeseburgers that had tomato. Then, this is:

$cheeseburgers\ with\ tomato=(180)(\frac{1}{2})=90$
