Answer:
[tex]2\frac{3}{4}[/tex]
Step-by-step explanation:
Given : You planned to work on a project for about 4 and a 1/2 hours today.
To Find :If you have been working on it for 1 and 3/4 hours, how much more time will it take?
Solution:
Total time to be spent on project today = [tex]4\frac{1}{2}=\frac{9}{2} hours[/tex]
You have been working on it for hours = [tex]1\frac{3}{4}=\frac{7}{4} [/tex]
Remaining time = [tex]\frac{9}{2} -\frac{7}{4} [/tex]
= [tex]\frac{11}{4}[/tex]
= [tex]2\frac{3}{4}[/tex]
Hence it will take [tex]2\frac{3}{4}[/tex] hours more .
