150 because
45/x=30/100 =
30x=4500
divide both by 30
and x=150
I'm pretty sure it's 3,000,000, "Basically, if the power is positive, you move the decimal point in the integer that many places to the right ex:
3.14 x 10 ^ 3 would be 3140.
If the power is negative, you move the decimal point to the left ex:
3.14 x 10 ^ -3 would be 0.000314" according to Yahoo

Finding the Number
To find the number, we have to translate the problem above to an algebraic equation. The algebraic equation refers to the statement of the equality of two algebraic expressions.
Equation:
Let "x" be the number.
4 is divided by a number - 4/x
3 divided by the number decreased by 2 - 3/x-2
"4 is divided by a number is equal to 3 divided by the number decreased by 2"
4/x = 3/x-2
Solution:
Cross multiply.
4/x = 3/x-2
x(3) = 4(x-2)
3x = 4x - 8
(Combine similar terms.)
3x - 4x = - 8
- x = - 8
- x/- 1 = - 8/- 1
x = 8
Final Answer:
8
Checking:
4/x = 3/x-2
4/8 = 3/8-2
1/2 = 3/6
1/2 = 1/2 ✔
