Question

7. A frying pan can hold 2 dozen wantons at a time.

It takes 5 minutes to fry 2 dozen wantons. How
long will it take to fry 40 dozens wantons​

Answer 1

100 minutes (1 hour & 40 minutes).

Explanation:

5 minutes = 2 dozen, which means it takes 2.5 minutes to cook 1 dozen.

2.5 minutes x 40 dozen = 100 minutes...

Answer 2

100 minutes

Explanation:

This is because it takes 5 minutes to fry 24 wantons, so we can write 5/24. Now we need to find out how long it takes to fry 40 dozen wantons, or 480 wantons. We can rewrite this as x/480. Since the time should be proportional, we get the following:

5/24 = x/480

We can now cross multiply. 24x=5x480. Therefore, 24x = 2400. If we divided each side by 24, we would get 100. Therefore, it takes 100 minutes to fry 40 dozen wantons, or about 1 2/3 hours.
