Juan spent 1 1/2 hours working on a project on monday, 2 hours on tuesday, and 2 3/4 hours on thursday. how many hours did it take him to finish the project?

8 1/4 hours

Step-by-step explanation:

This is how you solve it

you need a common denominator for 1 1/2 and 2 3/4 so you can do 4

1 1/2 •2= 1 2/4

so 1 2/4 + 2 3/4 = 3 1/4 then you add 2 so 5 1/4

the answers would be - 5 1/4

8 1/4 hours

Step-by-step explanation:

16.00 hours! Glad it wasn't me!

Step-by-step explanation:

Multiply 5 hours by 3.20

16.00 hours! Glad it wasn't me!

First, find 20% of 5 hours. 20% is also 1/5 of something, and 1/5 of 5 is 1.

Multiply 5 by 3 for the 300%, getting 15 hours, and add 1 for the 20%.

He spent 16 hours on the project. Hope this helps!
