You planned to work on a project for about 4 and a 1/2 hours today.
zzz [600]

Answer:

2\frac{3}{4}

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 = 4\frac{1}{2}=\frac{9}{2} hours

You have been working on it for hours =  1\frac{3}{4}=\frac{7}{4}

Remaining time =  \frac{9}{2} -\frac{7}{4}

                        =  \frac{11}{4}

                        =  2\frac{3}{4}

Hence it will take  2\frac{3}{4} hours more .
