7 times what equals 1?

Arturiano [62]

For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:
$(7) (x) = 1
$
From here, we clear the value of x.
We have then:
$x = \frac{1}{7} 
$
Therefore, we have:
$(7) ( \frac{1}{7} ) = 1
$
Answer:
7 times 1/7 equals 1
