How do you know if the equation for a problem is multiplication? Well, lets go and review: Multiplication is :<span>A </span>mathematical<span> operation performed on a pair of numbers in order to derive a third number called a product. For positive integers, </span>multiplication<span> consists of adding a number (the multiplicand) to itself a specified number of times. Thus </span>multiplying<span> 6. :)</span>

Hope this helps. (:
<span>Example: 56.25%/100 = .5625, Next, count the number of digits to the right of the decimal point, say that number is n, and multiply and divide the decimal by 10^n. For your example n = 4 so multiply and divide the decimal by 10^4, which is 10000, giving 5625/10000 which is the fraction sought. This last operation converts the decimal fraction to a whole number needed for the numerator of the fraction. </span>
