The number should be multiply is 10.

What is multiplication?

In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The twofactors and the product are parts of a multiplication problem.

Given:

n=0.9

Now, there is one number behind decimal point.

So, we have to multiply it by 10 to convert it into fraction from decimal.

Thus,

10n = 0.9*10

10n = 9

n = 9/10

Hence, the number must be multiplied is 10

as a puppy, kim's dog weighs 15 ounces. as an adult, kim's dog weighs 8 pounds. how many ounces did kim's dog gain

Answers

The answer is 113 ounces.

Kim's dog weighs 8 pounds. Since 1 pound is 16 ounces, Kim's dog weighs 8 × 16 ounces = 128 ounces.
As a puppy, Kim's dog weighs 15 ounces.
So, the weigh that Kim's dog gained is subtraction of 128 ounces and 15 ounces:
128 ounces - 15 ounces = 113 ounces.

Therefore, Kim's dog gained 113 ounces.

Answer:

113 ounces
