Question

What the answer if number 8

Answer 1

2.9375 pounds or
`2(15)/(16)` pounds.

Explanation:

We know that Pedro's puppy weighed
`6(1)/(8)` pounds in his first vet visit while on his second visit, he weighed
`9(1)/(16)` pounds and we to find his weight gain.

To find the weight gained by Pedro's puppy, we simply need to find the difference of his two weights.

Converting mixed numbers into decimal number and then taking their difference out:

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

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

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

Answer 2

Answer: 2.93 lb

Explanation:

1. To solve this problem you can rewrite the pounds given in the problem as a simple fractions:

`6^{(1)/(8)}`
`=((6*8)+1)/(8)=(49)/(8)`

`9^{(1)/(16)}`
`=((9*16)+1)/(16)=(145)/(16)`

2. Now, you must subtract both weights to calculate the difference, as following. Then, you have the result shown below:

`(145)/(16)lb-(49)/(8)lb=(47)/(16)lb=2.93lb`
