Question

Can you help me understand how to do this please?

Answer 1

Answer:

1/8

Step-by-step explanation:

The given expression is:

`-(1)/(4)+(3)/(8)`

Find the Least Common multiple(LCM) of the denominators

LCM of 4 and 8 = 8

After simplification, the addition expression then becomes:

`\begin{gathered} (-2(1)+1(3))/(8) \\ =(-2+3)/(8) \\ =(1)/(8) \end{gathered}`
