Answer:

3/8

Explanation:

Let the number be x.

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

Therefore:

[tex]\frac{2}{5}x=\frac{3}{20}[/tex]

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

[tex]\begin{gathered} 2x\times20=3\times5 \\ 40x=15 \end{gathered}[/tex]

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

[tex]\begin{gathered} \frac{40x}{40}=\frac{15}{40} \\ x=\frac{3}{8} \end{gathered}[/tex]

The number is 3/8.
