Question

8/9=4/5k how to solve

Answer 1

Divide both sides by 4/5 or multiply by the reciprocal.

Flip 4/5 to get the reciprocal.
The reciprocal of 4/5 is 5/4 so we will multiply both sides by that.

5/4 * 8/9 = 4/5 * 5/4 * k

4/5 and 5/4 cancel out so now you have


5/4 * 8/9 = k

multiply top and bottom
(5 *8 )/(4*9)

40/36

Simplify

10/9
