Question

During his first vet visit, Pedro's puppy weighed `6 1/8` pounds. On his second visit, he weighed `9 1/16` pounds. How much weight did he gain between visits?

Answer 1

The amount of weight gain is the difference between his second visit weight minus his first visit weight i.e. `2 15/16` pounds

Explanation:

[Allow me to apologize in advance for the excessive detail, but I wasn't sure where you might run into problems.]

Since `6 1/8` is the same as `6 2/16`

`9 1/16 - 6 1/8`
`color(white)("XXX")=(9+1/16)-(6 + 2/16)`

`color(white)("XXX")=(9-6)+(1/16-2/16)`

`color(white)("XXX")=3 - 1/16`

`color(white)("XXX")=2+1 -1/16`

`color(white)("XXX")=2+(16/16-1/16)`

`color(white)("XXX")=2+15/16`

`color(white)("XXX")=2 15/16`
