If 10% of 10% of a certain number is 2,
this certain number is...
A.)20
B.)100
C.)120
D.)200
0.1 x 0.1 x = 2
0.01 X = 2
X = ?
To find the value of the certain number, we need to work backwards from the information given.
If 10% of 10% of the certain number is 2, we can first find the value of 10% of the certain number.
To find 10% of a number, you can multiply the number by 0.1.
So, 10% of the certain number is 0.1 * x, where x represents the certain number.
Now, if 10% of that 10% is 2, we can set up an equation:
0.1 * (0.1 * x) = 2
Simplifying the equation, we get:
0.01 * x = 2
To solve for x, we can divide both sides of the equation by 0.01:
x = 2 / 0.01
x = 200
Therefore, the certain number is 200.
So, the correct answer is D.)200.
