Question

How do you evaluate `((\frac { 1} { 2} - \frac { 1} { 4} ) + 2) \times \frac { 1} { 2}`?

Answer 1

`=9/8`

Explanation:

`(color(red)((1/2-1/4)) +2) xx 1/2" "larr` start with the inner-most bracket

`=(color(red)(1/4)+2) xx 1/2" "larr` simplify the bracket

`= 2 1/4 xx1/2`

`= 9/4 xx 1/2`

`=9/8`
