From the problem :
![1-(7)/(8)=](https://img.qammunity.org/2023/formulas/mathematics/high-school/gcbqlg47jl72hes2bw2nz02r64rbwuzzg0.png)
Adding and substracting fractions need to have the same denominator.
Express 1 as a fraction with 8 as the denominator.
Note that :
![1=(8)/(8)](https://img.qammunity.org/2023/formulas/mathematics/college/9p8n3acbpk4h5p4td04ur49ymf3txctzd9.png)
1 is equal to 8 divided by 8
Replace it from the equation :
![\begin{gathered} 1-(7)/(8) \\ \Rightarrow(8)/(8)-(7)/(8) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/7c9idqc5v5cgnztzczcnnwm7lx1dg8wut1.png)
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 :
![(8)/(8)-(7)/(8)=(1)/(8)](https://img.qammunity.org/2023/formulas/mathematics/high-school/sd436c51i483eehvw26uvei6jjllg2m7jr.png)
The answer is 1/8
