and french fries weigh?
The meal will weigh 'pounds.

Answer 1

7/12 pounds

Explanation:

1/3 * 1 = 1/3

1 = 4/4

then

1/3 * 4/4 = 1/3

1/3 * 4/4 = (1*4)/(3*4) = 4/12

1/3 = 4/1|2

1/4 * 3/3 = (1*3) / (4*3) = 3/12

1/4 = 3/12

then:

1/3 + 1/4 = 4/12 + 3/12 = (4+3)/12 = 7/12

The meal will weigh 7/12 pounds.
