Answer:
4 1/8 inches
Step-by-step explanation:
1. Make each a fraction with the same denominator so that you can add and subtract them easily
[tex]1 \frac{1}{2}=\frac{12}{8}[/tex]
[tex]3 \frac{4}{8}=\frac{28}{8}[/tex]
[tex]\frac{7}{8}=\frac{7}{8}[/tex]
2. Add together the amount of snow that fell in the first 2 hours
[tex]12/8+28/8=40/8[/tex]
3. Subtract the amount of snow that melted in the third hour because no snow continued to fall
[tex]40/8-7/8=33/8[/tex]
4. Convert the "improper fraction"
[tex]33/8=4\frac{1}{8}[/tex]
