$r - \frac{7}{8} > 1$

Step 1

Add $\frac{7}{8}$ to both sides of the inequality.

$r > 1 + \frac{7}{8}$

Step 2

Write $1$ as a fraction with a common denominator.

$r > \frac{8}{8} + \frac{7}{8}$

Step 3

Combine the numerators over the common denominator.

$r > \frac{8 + 7}{8}$

Step 4

Add $8$ and $7$ .

$r > \frac{15}{8}$

Step 5

The result can be shown in multiple forms.

Inequality Form:

$r > \frac{15}{8}$
