Question

During a certain day, a worker made 81 parts. He usually does 45 parts per day. What was the percent by which he increased the number of parts he usually makes?

Answer 1

45/81 = .55
Turn this into a percent: .55 x 100
55 percent
Hope this helps!

Answer 2

The equation would be 
45/81 that gives you
0.5555555555 
Since you have to round it to the nearest hundredth to get the percentage it would result in 0.56
Then you have to turn 0.56 into a percent so it would result in 
56% ←Thats your answer
