We're going to use the 'KCF' method to solve this question.

We keep the first fraction,
(9)/(10).

Then, we change the sign to the opposite of it, which would be multiplication.

(9)/(10) x

Finally, we flip the last fraction, having the denominator at the top to be the numerator and the numerator at the bottom to be the denominator.

(9)/(10) x
(4)/(3)

At the end, we multiply straight across:

(9)/(10) x
(4)/(3) =
(36)/(30)

* Remember, we only use KCF in dividing fractions

So our final answer is
(36)/(30) until you simplify it.


(36)/(30) = 1
(1)/(5)

Hope this helps!~

To divide fractions multiply by the reciprocal of the second fraction.
A reciprocal is the reverse of a fraction, for example, the reciprocal of 2/3 is 3/2.

So,

9 3 27
__ x _ = __
10 4 40

The answer is 27/40.

Hope this helped! Please comment or DM me if you have anymore questions or don't understand. :)
