Tim has completed greater amount of work and overall they have completed 142/143 of the project work
Step-by-step explanation:
Given
Work completed by Jaime = j = 5/11
Work completed by Tim = t = 7/13
<u>a. Who has completed the greater amount of work?</u>
In order to see that we have to convert the fractions in decimal
So,
j = 5/11 = 0.45
t = 7/13 = 0.53
As we can see that the decimal for Tim's work space is large, Tim has completed greater amount of work
b. How much of the project have they completed together? Show your work.
