Question

A number multiplied by 2/5 is 3/20, Find the number

Answer 1

3/8

Step-by-step explanation:

Let the number be x.

A number multiplied by 2/5 = (2/5)x

Therefore:

`(2)/(5)x=(3)/(20)`

To solve for x, first, we cross-multiply.

`\begin{gathered} 2x*20=3*5 \\ 40x=15 \end{gathered}`

Next, we divide both sides of the equation by 40.

`\begin{gathered} (40x)/(40)=(15)/(40) \\ x=(3)/(8) \end{gathered}`

The number is 3/8.
