Hello!
We can write this as an equation below.
0.2x=100
To solve, we just divide both sides by 0.2
x=500
Therefore, our answer is 500.
I hope this helps!
Let's assume the number be x.
Hence, the problem is to find 20% of x that equal to 100.
Hence, we can set up the equation as following:
20% of x = 100
0.20 * x = 100 Since 20%= 20/100 = 0.20
Dividing each sides by 0.20 to isolate x.
[tex] \frac{0.20x}{0.20} =\frac{100}{0.20} [/tex]
So, x = 500 By simplifying.
Hence, the number is 500.
