Question

7 times what equals 1?

Answer 1

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

Answer 2

The answer is 1/7.
If you do 7/1 times 1/7
7 times 1 equals 7
1 times 7 equals 7
7/7 when simplified is 1
