Answer 1

-9/20÷x=-3/2

-9/20=-3/2×x

when -3/2 cames to L.H.S side it becomes -2/3

-9/20×-2/3=x

we cancel the denominator of -9/20(20) with the numerator of -2/3(-2)

and we cancel the numerator of-9/20(-9) with the denominator of -2/3(3)

3/10=x

finally, the required number be x is 3/10

therefore,3/10 divided -9/20 we get -3/2
