You work for a packaging company. The total weight of a container and its contents is 48 pounds. The container accounts for [tex]\frac{13}{16}[/tex] of the total weight.

Which fraction represents the ratio of the weight of the container to the weight of the contents?

A. [tex]\frac{9}{39}[/tex]
B. [tex]\frac{9}{30}[/tex]
C. [tex]\frac{30}{48}[/tex]
D. [tex]\frac{39}{9}[/tex]
E. [tex]\frac{48}{9}[/tex]



Answer :

To find the ratio of the weight of the container to the weight of the contents, follow these steps:

1. Calculate the weight of the container:
The weight of the container accounts for [tex]\(\frac{13}{16}\)[/tex] of the total weight. Given the total weight is 48 pounds, we can calculate the weight of the container as follows:
[tex]\[ \text{Weight of the container} = \frac{13}{16} \times 48 = \frac{13 \times 48}{16} \][/tex]
Simplify the fraction inside the multiplication first:
[tex]\[ \frac{48}{16} = 3 \][/tex]
Now multiply:
[tex]\[ \text{Weight of the container} = 13 \times 3 = 39 \text{ pounds} \][/tex]

2. Calculate the weight of the contents:
Subtract the weight of the container from the total weight:
[tex]\[ \text{Weight of the contents} = 48 - 39 = 9 \text{ pounds} \][/tex]

3. Calculate the ratio of the weight of the container to the weight of the contents:
The ratio is given by:
[tex]\[ \text{Ratio} = \frac{\text{Weight of the container}}{\text{Weight of the contents}} = \frac{39}{9} \][/tex]

4. Identify the correct fraction from the given options:
The possible options were:
- [tex]\(\frac{9}{39}\)[/tex]
- [tex]\(\frac{9}{30}\)[/tex]
- [tex]\(\frac{30}{48}\)[/tex]
- [tex]\(\frac{39}{9}\)[/tex]
- [tex]\(\frac{48}{9}\)[/tex]

From our calculation, the ratio of the weight of the container to the weight of the contents is [tex]\(\frac{39}{9}\)[/tex].

Thus, the fraction that represents the ratio of the weight of the container to the weight of the contents is [tex]\(\boxed{\frac{39}{9}}\)[/tex].
