Chapter 6.1, Problem 64CCR

To determine

Calculate the sum or difference and also do in simplest form.

Answer to Problem 64CCR

The solution for the expression is $\frac{-3}{8}$ .

Explanation of Solution

Given: It is given in the question that the expression is $\frac{1}{2}-\frac{7}{8}$ .

Concept Used:

In this, use the concept of subtraction and also make the lowest form by dividing with suitable number.

Calculation:

Here, the denominator are different. So set both Equations to the LCM between them. The LCM of $2$ and $8$ is $8$ .so,

  $\frac{1}{2}\cdot \frac{4}{4}=\frac{4}{8}$

  $\begin{array}{l}\frac{4}{8}-\frac{7}{8}\\ =\frac{4-7}{8}\\ =\frac{-3}{8}\end{array}$

Conclusion:

The solution is $\frac{-3}{8}$ .
