Verified Answer :

When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.

The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.

for example, the reciprocal of 9/10 is 10/9

Knowing this information 4/5÷9/10 is the same as 4/5×10/9

Now we can solve...

\(\frac{4}{5} * \frac{10}{9} = \frac{40}{45} = \frac{8}{9}\)

Answer= 8/9

8/9 is the answer to your question
