Answer 8

Use your facts:

There are: 96 metal disks

They are: 3/8 of an inch thick

What is thickness?

96 x 3/8 = ?  

Go with the facts:

There is: 64 gal tank (this fact is not needed)

there are: 45 gal in tank  (this fact is the quantity)

There was: 4/5 sold

What is 4/5 of 45 gal?

Your turn good luck

Answer 9

To solve these, multiply by the numerator and then divide by the denominator.

Answer 10

1. 96 x 3.8 = X inches

2. 45/64 x 5/4 = answer

Answer 11

36, 36

Answer 12

The first answer is 36" you see 3x96=288 so all the plates together are 288/8 of an inch since 1 inch is 8/8 you divide 288 by 8 and that gives you the amount of whole inches.

4/5 of 45 gallons is 36 gallons, you see if you divide 45 by 5 that tells you what 1/5 of 45 is which is 9 then if you want to find what 4/5 is you simply multiply 9 times 4 which is 36.

4/5 of 64 is 51.2 you try it and see if you come up with the same thing
