1/7 = something over 7
What over 7 is the same thing as 1 over 7?

Answer 3

Alternatively you could cross-multiply and get
7x = 7
Divide both sides by 7 and you get
x = 1

Answer 4

Answer 5

Answer 6

Ok let's see, if you put in 7 for z, then you get
\[\frac{ 7 }{ 7} = \frac{ 1 }{ 7}\]
That's not right is it?

Answer 7

It's 1!

Answer 8

Ok , i see. Thank you @sandsalamand & @ijakez

Yes, because if you put in 1 for z then you get
\[\frac{ 1 }{ 7 } = \frac{ 1 }{ 7}\]
