Answer 1

if the quotient of 8/13 and 2 is subtracted from the product 7/4 and 8/21 the difference is 14/39

Answer 2

Given:

The quotient of
`(8)/(13)` and 2 is subtracted from the product of
`(7)/(4)` and
`(8)/(21)`.

To find:

The difference.

Solution:

The quotient of
`(8)/(13)` and 2 is subtracted from the product of
`(7)/(4)` and
`(8)/(21)`.

`(7)/(4)* (8)/(21)-((8)/(13))/(2)`

`=(1)/(1)* (2)/(3)-(8)/(13* 2)`

`=(2)/(3)-(4)/(13)`

`=(26-12)/(39)`

`=(14)/(39)`

Therefore, the difference is
`(14)/(39)`.
