48 divided by four fifths

Fed [463]

Answer:

The answer is 60.

Step-by-step explanation:

$\frac{48}{1}$ ÷ $\frac{4}{5}$

Now, apply the fraction rule(\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}):

$\frac{48}{1}$ × $\frac{5}{4}$

Cross-cancel(common factor of 4):

$\frac{12}{1}$ × $\frac{5}{1}$

Multiply:

$\frac{12 x 5}{1 x 1}$

Simplify:

12 x 5=60

The answer is 60
