# What is 4.0 divided by 0.05?

80

#### Explanation:

There are two ways to do this:
$\frac{4}{0.05}$

1) we can think of the $0.05$ as a fraction $\frac{5}{100}$. If we then write the fraction as $\frac{4}{\frac{5}{100}}$ we can use a property of fractions when they are in the denominator, which is, we flip them upside down and multiply by the numerator, making it look like this: $4 \cdot \frac{100}{5} = 4 \cdot 20 = 80$

2) we can multiply the top and bottom of that by 100 leaving us with $\frac{400}{5} = 80$
