A/5 divided by 3/10a if a does not equal 0? What is the answer?

lidiya [134]

Answer:

The answer is $\frac{2}{3}$

Step-by-step explanation:

When we divide two fractions, we multiply the numerator by the inverse of the denominator. So

$\frac{\frac{a}{5}}{\frac{3a}{10}} = \frac{a}{5} \times \frac{10}{3a} = \frac{10*a}{5*3a} = \frac{10a}{15a} = \frac{2}{3}$

The answer is $\frac{2}{3}$
