When fractions have the same denominator, the larger fraction is the one with the larger numerator  

therefore

Tim has completed the greater amount of work

we have that

Jaime has 65/143 of a project completed  

Tim has 77/143 of a project completed  

Sum the fraction of the project completed by Jaime plus the fraction of the project completed by Tim
