4.8 quarts (16 times 3/10)

Answer 2

Hello there!

The information given to us is:

- The mixture has 30% alcohol

- There is 16 quarts of it

One way to do it:

Multiply 30% by 16 to get what 30% of 16 is.

30% * 16 = 4.8

Another way to do it:

What is 10% of 16?

10% of 16 is 1.6, because 10 of 1.6 is 16.

How many 10%s become 30%?

3 10%s make a 30%.

Since 10% = 1.6, and 3 10%s make 30%, 3 1.6s must make 30%.

3 1.6s is 4.8, because 1.6 + 1.6 + 1.6 = 4.8.

Therefore, your answer is 4.8 quarts.
