Question

Simplify 7/9 • 3/4 • 2/7

Answer 1

`(1)/(6)`

Explanation:

`(7)/(9)` ×
`(3)/(4)` ×
`(2)/(7)`

the 7 on the numerator/ denominator cancel to 1

the 3 and 9 cancel ( 3 → 1 and 9 → 3 )

the 2 and 4 cancel ( 2 → 1 and 4 → 2 )

=
`(1)/(3)` ×
`(1)/(2)` ×
`(1)/(1)`

multiply the remaining values on the numerators/ denominators

=
`(1(1)(1))/(3(2)(1))` =
`(1)/(6)`
