Question

Which operation is equivalent to dividing by 1/5

Answer 1

$\huge{\boxed{\text{multiplying by 5}}}$

To divide by a fraction, you start by changing the operation from multiplication to division.

Then, find the reciprocal of the fraction after the $\div$, which means you flip its numerator and denominator. The numerator is the top number and the denominator is the bottom number.

$\div\frac{1}{5}\ =\ *\frac{5}{1}$

If a fraction has a denominator of $1$, you can remove the denominator, leaving just the numerator.

$*\frac{5}{1}\ =\ \boxed{*5}$
