Ink cartridges weigh 1/8 pound. the total weight of the cartridges in a box is 4 1/2 pounds. how many cartridges does the box contain? show your work and explain why you chose the operation you did.

Answer 1

1/8x=4.5x (x is the number of cartridges)
Multiply both sides by 8
x=36
The box contains 36 cartridges.

Answer 2

Answer: There are 36 cartridges that box contain.

Explanation:

Since we have given that

Weight of ink cartridges =
`(1)/(8)` pounds

Total weight of the cartridges in a box =
`4(1)/(2)=(9)/(2)\ pounds`

so, Number of cartridges that box contain is given by

`(9)/(2)/ (1)/(8)\\\\=(9)/(2)* (8)/(1)\\\\=9* 4\\\\=36`

Hence, there are 36 cartridges that box contain.
