50 Divided By ? = 2.5

50 divided by 10 = 5 and so 50 divided by 20 = 2.5.    Answer is 20.

50/x = 2.5   x =20

50 divide x = 2.5
                50 = 2.5(x)
                50 = 2.5x
                50/2.5 = x
                20 = x

?=20

That is an easy one. The answer is 20

20

50/x = 2.5

50/2.5 = x

x = 20

hence,
50 divided by 20 = 2.5

In 6 / ? = 2 you know ? = 3 and 6 / 2 = 3 so 6 / 2 = ?.
In the same way 50 / ? = 2.5 so 50 / 2.5 = ?.
50 / 2.5 = 20

50 divided by 20 equals 2.5

20 (20x2.5=50)
