From the problem :
[tex]1-\frac{7}{8}=[/tex]
Adding and substracting fractions need to have the same denominator.
Express 1 as a fraction with 8 as the denominator.
Note that :
[tex]1=\frac{8}{8}[/tex]
1 is equal to 8 divided by 8
Replace it from the equation :
[tex]\begin{gathered} 1-\frac{7}{8} \\ \Rightarrow\frac{8}{8}-\frac{7}{8} \end{gathered}[/tex]
Since the denominators are now the same, perform the operation for the numerator, in this case 8 - 7 = 1
then copy the denominator.
The result will be :
[tex]\frac{8}{8}-\frac{7}{8}=\frac{1}{8}[/tex]
The answer is 1/8
