Question

Simplify the expression⅜b - ¾b

Answer 1

Answer:

-3b / 8

Explanations:

The given expression is:

`(3)/(8)b\text{ - }(3)/(4)b`

Which can be re-written as:

`(3b)/(8)-(3b)/(4)`

Note that the LCM of 8 and 4 is 8

Therefore, the expression can be simplified as:

`\begin{gathered} (3b-2(3b))/(8) \\ (3b-6b)/(8) \\ (-3b)/(8) \end{gathered}`

The simplified expression is -3b/8
