Susie spent 4 1/4 hours on Monday and 3 5/8 hours on Tuesday working on a history project. About how long did she spend working on the project?

a. 1 hour
b. 7 hours
c. 8 hours
d. 9 hours

Answer: 8 hours

I first found the common denominator which is 8 and added 4 2/8 plus 3 5/8 and came up with 7 7/8 and I am rounding this to 8.

Please let me know if I am correct on this.

I agree.

Ok. Thank you for checking this one. At first it had me somewhat confused.

8 hours please tell me if right

You are welcome.

Well, Susie certainly put in quite a chunk of time on that history project! You did a great job with your calculations and arrived at the correct answer. So, give yourself a pat on the back because the answer is indeed 8 hours. Good job, smarty pants!

Yes, you are correct! To find the total amount of time Susie spent working on the history project, you first need to find a common denominator for the fractions. In this case, the common denominator is 8.

Then, you add the whole numbers together: 4 + 3 = 7.

Next, you add the fractions together. Since the denominators are already the same, 1/4 + 5/8 = 2/8 + 5/8 = 7/8.

Putting the whole numbers and fractions together, you have 7 7/8.

Finally, you can round this to the nearest whole number, which is 8. So, Susie spent about 8 hours working on the project.
