Question

Plz help with number nine plz thank u!

Answer 1

`7(7)/(8)`

Explanation:

The first thing we should do is find the difference between
`3(3)/(4)` and
`5(1)/(8)`. This will give us the first equation that was used in this problem.

`5 (1)/(8) -3(3)/(4) =1(3)/(8)`

`6(1)/(2) -5(1)/(8) =1(3)/(8)`

If needed, you should change the fractions so all of the fractions have the same denominator.

`3(3)/(4) =3(6)/(8)`

`6(1)/(2) =6(4)/(8)`

Re-did Equation:

`5(1)/(8) -3(6)/(8)`

`6(4)/(8) -5(1)/(8)`

If you want to make it even easier, you should make them improper fractions, them convert them back to mixed numbers at the end.

Improper:

`3(6)/(8) =(30)/(8)`

`5(1)/(8) =(41)/(8)`

`6(4)/(8) =(52)/(8)`

Revised:

`(41)/(8) - (30)/(8) =(11)/(8)`

`(52)/(8) -(41)/(8) =(11)/(8)`

`(11)/(8) =1(3)/(8)`

If we want to find how big the puppy will be in another week, we will add
`(11)/(8)` to
`(52)/(8)` to get the weight. We can then make this into a mixed number.

Answer Equation:

`(52)/(8) +(11)/(8) =(63)/(8)`

Mixed number:
`7(7)/(8)`

I hoped this helped. :)
