Answer:

[tex]18\frac{1}{8}[/tex]

Step-by-step explanation:

Make a common denominator of 8.

[tex]17\frac{1}{4} = 17\frac{2}{8}[/tex]

Change the mixed number to an improper fraction.

[tex]17\frac{2}{8} = \frac{138}{8}[/tex]

Add the numbers together

[tex]\frac{138}{8} + \frac{7}{8}[/tex]

Figure out the answer in improper fractions.

[tex]\frac{138}{8} + \frac{7}{8} = \frac{145}{8}[/tex]

Divide 145 by 8.

[tex]\frac{145}{8} = 18\frac{1}{8}[/tex]

The answer is [tex]18\frac{1}{8}[/tex].
