What is 9/10 divided by 2/5
\(\frac{9}{10}:\frac{2}{5}=\frac{9}{10}*\frac{5}{2}= \boxed{\frac{9}{4}}\)
Dividing a fraction by a second fraction is the same as multiplying the first by the reciprocal of the second:
\(\frac{9}{10} / \frac{2}{5}\)
= \(\frac{9}{10} * \frac{5}{2}\)
= \(\frac{45}{20}\)
= \(\frac{9}{4}\)
Hope this helps! :)
