Answer:
A rational number is a number that can be express as the ratio of two integers.
Step-by-step explanation:
A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever).
20 percent is 1/5, so we'd multiply 60 by 5.
60x5=300
60 minutes is 20% of 300
