[tex]\frac{3}{4}[/tex] of the homework is left to finish.
Explanation:
The total homework is 1.
The completed homework is [tex]\frac{1}{4}[/tex].
To find the how much of homework is left to complete, we need to subtract the total homework and the completed homework.
Thus, we have,
[tex]1-\frac{1}{4}[/tex]
Taking LCM, we have,
[tex]\frac{4-1}{4}[/tex]
Subtracting, we have,
[tex]\frac{3}{4}[/tex]
Thus, the homework left to finish is [tex]\frac{3}{4}[/tex].
