Answer:
To divide any number by a fraction:
Multiply the number by the reciprocal of the fraction.
Simplify the resulting fraction if possible.
Check your answer: Multiply the result you got by the divisor and be sure it equals the original dividend.
You can only divide by non-zero fractions.

Answer:
Division and multiplication are inverse operations. This means they "undo" each other. You can check your answer by multiplying the quotient by the divisor. You should get the dividend.
