what is the difference between 3/4 and 20%?
Answers
Answer:
To find 3/4 of 20 you can use proportion system
3:4 = x : 20
So you put first the part (3) in ratio with the total (4) equal to a part that you want to find denoted by x in ratio with the total (20). Using the properties of multiplying the middle terms between each other and the extremes by each other you get
4x= 20 • 3
Make x the subject
x= (20•3)/4
x= 60/4
x=15
3/4 of 20 is 15
