Explanation:

`1 (1)/(2) + 2 (1)/(2) * (3)/(4) - (1)/(2)`

Convert the mixed number to an improper fraction

`(3)/(2) + (5)/(2) * (3)/(4) - (1)/(2)`

Multiply the fractions

`(3)/(2) + (15)/(8) - (1)/(2)`

Calculate the sum

`(3 * 4 + 15)/(8) - (1)/(2)`

`(12 + 15)/(8) - (1)/(2)`

Add the numbers

`(27)/(8) - (1)/(2)`

Calculate the difference

`(27 - 1 * 4)/(8)`

`(27 - 4)/(8)`

`(23)/(8)`

Hope this helps...
