Question

Can you please help me?

Answer 1

So for this you just want to divide 4/5 by 9/10 because it is the opposite of the equation.

9/10 / 4/5

To divide fractions, you just multiply and reverse the second fraction.

For example:

9/10 * 5/4

Now you can just normally multiply.

45/40

Or, simplified,

9/8

(Or 1 1/8)
