Question

What the answer if number 8

Answer 1

Pedro's puppy gained 2.9375 pounds.

Explanation:

We are given that in his first visit to vet, Pedro's puppy weighed
`6(1)/(8)` pounds while on his second visit, he weighed
`9(1)/(16)` pounds.

In order to find the weight gained by Pedro's puppy, we will find the difference between the two weights of the puppy.

Converting the mixed fractions into decimal number to make the calculations easier and then taking their difference out:

`6(1)/(8)` = 6.125

`9(1)/(16)` = 9.0625

So Pedro's weight gain = 9.0625 - 6.125 = 2.9375 pounds or
`2(15)/(16)` pounds.

Answer 2

2 15/16 pounds

Explanation:

To determine the weight gain, we subtract the larger wieght from the smaller weight.

9 1/16 - 6 1/8

We need to get a common denominator of 48

9 1/16*3/3 - 6 1/8 *6/6

9 3/48 - 6 6/48

Since the second fraction is larger than the first fraction we have to borrow from the 9 Replace it with 8 and add 48/48 to the 3/48

8 (3/48+48/4*) - 6 6/48

8 51/48 - 6 6/48

2 45/48

We can simplify the fraction by dividing by 3 on both the top and bottom

2 15/16 pounds
