For this case we can define the following variable:
x: unknown number
We write the equation that models the problem:
[tex] (\frac{1}{10}) * x = 0.04
[/tex]
From here, we clear the value of x.
We have then:
[tex] x = 0.04 * 10
x = 0.40
[/tex]
Answer:
Completing the sentence we have:
0.04 is 1/10 of 0.40
