To divide fractions, you multiply the first fraction by the reciprocal of the second fraction. So, 9/10 ÷ 2/5 can be written as 9/10 * 5/2.

Multiplying the numerators, we get 9 * 5 = 45.
Multiplying the denominators, we get 10 * 2 = 20.

So, 9/10 ÷ 2/5 = 45/20.

However, this fraction can be simplified by dividing both the numerator and denominator by 5.

45 divided by 5 is 9, and 20 divided by 5 is 4.

So, 9/10 ÷ 2/5 = 9/4.

Therefore, the answer is 9/4.
