Question

Simplify the equation

Answer 1

1z or z

Explanation:

Because the equation is all multiplication, it's

`(6)/(7)` ×
`(7)/(6)`×z

6/7 times 7/6 = 1

z is an unknown number, so you cannot simplify it more.

Answer 2

Given:
6/7(7/6z)
First, you would have to multiply both fractions together:
6/7(7/6z) = 42/42z
Next, simplify:
1z
(Since 42/42 is a bit redundant, you would then simplify to 1z)

Finally, you can either leave the answer as 1z or you can just leave it as z, because in math, variables have an imaginary 1 in front of them so the 1 is not necessary.
Answer: z
