2.)Find the Least Common Denominator (LCD) of 9/16,1/4
Method 1: By Listing Multiples
List out all multiples of each denominator, and find the first common one.
16 : 16
4 : 4,8,12,16
Therefore, the LCD is 16
Method 2: By Prime Factors
List all prime factors of each denominator, and find the union of these primes.
16 : 2,2,2,2
4 : 2,2
Therefore, the LCD is 2×2×2×2=16
Make the denominators the same as the LCD
Simplify. Denominators are now the same
Join the denominators
so 5/16 would be your answer. do you see how I did it?
When subtracting or adding fractions, you need to make the denominators (the numbers on bottom) the same. To do that, you can multiply one or both of the fractions by a form of one , which can be 4/4, 5/5, or any number over itself. I multiplied 1/4 by 4/4 because 4*4 is 16, and you needed 16 to be your denominator. Get it?
