First, we need to convert the fractions to have a common denominator.

3/10 can be written as 30/100.
42/100 remains the same.

Now add the two fractions:

30/100 + 42/100 = 72/100.

Therefore, Casey has 72/100 gallon of red paint.
This can be simplified to 0.72 gallon.

So, the answer is:

C. 0.72 gallon

To add the amounts of red paint in both cans, we need to find a common denominator.

3/10 gallon can be written as 30/100 gallon.
42/100 gallon remains the same.

Now add the two fractions:

30/100 + 42/100 = 72/100.

Therefore, Casey has 72/100 gallon of red paint.

This can be simplified to 0.72 gallon.

So, the answer is:

C. 0.72 gallon

To find out how much cloth Greg has left after using 2 6/8 feet for the first blanket, we have to subtract that amount from 4 5/8 feet.

First, let's convert these mixed numbers to improper fractions.
4 5/8 = (8 * 4 + 5)/8 = 33/8
2 6/8 = (8 * 2 + 6)/8 = 22/8

Now, subtract 22/8 from 33/8:
33/8 - 22/8 = 11/8

Now, convert back to a mixed number:
11/8 = 1 3/8

Therefore, Greg has 1 3/8 feet of cloth left to use for the second blanket.
