Answer:
7/24
Step-by-step explanation:
Let the unknown number be x.
-18/7 x x = -15/20
x = -15/20 divided by -18/7
We take the reciprocal of -18/7 which is -7/18.
-15/20x (-7/18) = 105/360
When we simplify 105/360 we get 7/24.
105/360 = 7/24.
And the decimal form of 105/360 is 0.291667.
105/360 = 0.291667
