The percentage of questions Matt has answered is 80 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Number of questions Matt has answered = 20
Total number of questions = 25
Let the percentage of questions Matt has answered = x
Number of questions Matt has answered / Total number of questions = x %
Percentage of questions Matt has answered = ( Number of questions Matt has answered / Total number of questions ) / 100
x = ( 20 x 100 ) / 25
x = 20 x 4
x = 80 %
Hence, the percentage of questions Matt has answered is 80 %

1000 meters / 200 meters = 5 times in around the track for ONE kilometer.
To find how many times Julius would need to run around to reach THREE kilometers you simply do the following:
5 x 3 = 15 ---> Julius would need to run around the track 15 times in order to reach 3 kilometers.
