Answer:
28 is added by -8 equals 20
Step-by-step explanation:
The equation to calculate something added by -8 equals 20 is as follows:
x-8 = 20
x = 20+8
x = 28
28 is added by -8 equals 20
!5% is equivalent to 15 parts over the whole 100 part. It is written in proportions as 15/100.
Similarly, you need to find how many parts in 80 are equivalent to 15%or 15/100. So, just equate both equation with x as an unknown.
x/80 = 15/100
x = (15/100)*80
x = 12
Thus, the 15% of 80 is 12.
