Question

DeShawn uses 3/4 of a box of rice to cook dinner. The portion he uses weighs 12 ounces. Write and solve and equation to find the weight of the full box kf rice.

Answer 1

Answer:

$16\ ounces$

Step-by-step explanation:

we know that

$3/4$ of a box of rice weighs $12$ ounces

so by proportion

Find the weight of the full box of rice

$\frac{12}{(3/4)}\frac{ounces}{box} =\frac{x}{1}\frac{ounces}{box}\\ \\x=12/(3/4)\\ \\x=16\ ounces$

Answer 2

3/4 box = 12 oz

we first need to find 1/4 of a box. to do that divide both sides by 3

1/4 box = 4 oz

for a full box which is 4/4 multiply both sides by 4

1/4 x (4)  = 4 x (4) oz

4/4 ( or one whole) = 16 oz
