What percent of the project is completed?

Question

Sarah has a very large assignment to do that consists
of 245 problems. At the end of the week she has completed
120 of the problems. 

Answer 1

Set up a proportion:

 

120 is to 245 as x is to 100

 

120/245 = x/100

 

x = 100(120/245) ≅ 48.98%

Answer 2

120 / 245 = percent completed

 

Can you calculate?
