-1 and -120
The easiest way is to multiply the original number by 1.08. Otherwise, multiply the original number by .08 and add the resulting number to the original number.
Prime number
Multiply the number by 100 and add a percent symbol.
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.

3200 To solve this, multiply 8 and 4 and you will get 32. Then, you can add the two zeroes from 400

None of the factor pairs of 120 add up to -14. If that was -120, you could use -20 and 6.
Divide the number by 100 and then multiply the answer by 5. add the number with the answer.
-6 and -20
you can multiply by 2, or add 120, or divide by 1/2. I'd say it's best to multiply, or find the "product."
-15+-8=-23 -15*-8=120
12x10=120. The easiest way to multiply anything by 10 is to just add a zero on the end. So if you add a zero into 12 you'll get 120, which is your answer.
You can add them.
