Question

-5 1/2 - 2 1/3

Please do not answer -7.83333333333

Answer 1

- 7
`(5)/(6)`

Explanation:

Change the mixed numbers to improper fractions

5
`(1)/(2)` =
`(11)/(2)`

2
`(1)/(3)` =
`(7)/(3)`

-
`(11)/(2)` -
`(7)/(3)`

We require the denominators to be the same before adding

The lowest common multiple of 2 and 3 is 6, hence

= -
`(11(3))/(2(3))` -
`(7(2))/(3(2))`

= -
`(33)/(6)` -
`(14)/(6)`

=
`(-33-14)/(6)` = -
`(47)/(6)` = - 7
`(5)/(6)`
