If 20% of a number is 8, what is 25% of the number?

Sagot :

20%*x = 8

20% = 2/10

2/10*x = 8      |(*10/2)

2/10*10/2*x= 8 * 10/2                    2/10*10/2 =>1
1*x = 80/2
x=40

25% from 40 is 10
25% = 1/4
1/4 * 40 = 40/4 = 10

Answer:

Set up an equation as 0.2x = 8, which means 20 percent of x equals 8. Solve the equation by dividing each side by 0.2. Dividing 0.2 from each side results in x = 40. Eight is 20 percent of 40.
