Question

9/11 x 7/10 - 9/11 x 3/10

Answer 1

18/55

Explanation:

Answer 2

`(18)/(55)`

Explanation:

Given the following question:


`(9)/(11) *(7)/(10) -(9)/(11) *(3)/(10)`

Multiply the fractions, by multiplying the numerators by the numerators, doing the same with the denominators.


`(9)/(11) *(7)/(10)`

`9*7=63`

`11*10=110`

`=(63)/(110)`

`(63)/(110) -(9)/(11) *(3)/(10)`

`(9)/(11) *(3)/(10)`

`9*3=27`

`11*10=110`

`=(27)/(110)`

`(63)/(110) -(27)/(110)`

Now subtract:

`(63)/(110) -(27)/(110)`

`cd=110`

`63-27=36`

`=(36)/(110)`

Simplify:

`(36)/(110)`

`(36)/(110)/2=(18)/(55)`

`=(18)/(55)`

Hope this helps.
