Question

A horseshoe weighs 8.2 ounces The nails in the horseshoe weigh 0.12 ounces. What is the weight of the horseshoe without the nails?

Answer 1

Without the nails, the horseshoe weighs `8.08` ounces

Explanation:

To find the weight of the horseshoe without the nails, subtract the weight of the nails from the horseshoe's entire weight.

`color(white)(mmm.)` `8.20` ounces `larr` weight of horseshoe
`-` `color(white)(.n.)` `0.12` ounces `larr` minus weight of nails
`color(white)(mm.m)`―――
`color(white)(mm.m)` `8.08` ounces `larr` horseshoe without nails
