Question

Where should I insert parentheses brackets and braces in this problem 7x20/11-9 2/8

Answer 1

`[((7 * 20))/(11) - 9]`
`(2)/(8)` =
`(41)/(44)`

The given question can be expressed using the required parentheses if the final answer is known. But the problem can be expressed as:

`[((7 * 20))/(11) - 9]`
`(2)/(8)`

So that;

`[(140)/(11) - 9]`
`(2)/(8)`

`[(140 - 99)/(11)]`
`(2)/(8)`

`(41)/(11)` *
`(2)/(8)` =
`(82)/(88)`

=
`(41)/(44)`

Therefore, we have.

`[((7 * 20))/(11) - 9]`
`(2)/(8)` =
`(41)/(44)`
