Question

Hello can you explain this to me please. Simplify the Expression by combining like terms

Answer 1

EXPLANATION

Given the expression:

`(3)/(4)r\text{ +2r + }(1)/(2)r`

First, taking r as a common factor:

`r((3)/(4)+2+(1)/(2))`

Then, adding 3/4 with 2 as follows:

`(3)/(4)+2=(11)/(4)`

Replacing on the equation:

`r((11)/(4)+(1)/(2))`

Adding 11/4 and 1/2:

`(11)/(4)+(1)/(2)=(13)/(4)`

Replacing on the equation and removing the parentheses:

`(13)/(4)r`
