Subtracting+Fractions+=)


   Step 1. The denominators for all fractions has to be the same. To do that you need to find the common denominators. Common denominators, are when the denominator goes with the other denominator, without making a big mess. To find the common denominator you have to find a number that fits into both numbers. For example ; 1/2 and 1/5. 10, 20, 30 ; the lowest common denominator is 10. what ever you do in one side you have to do it in the other side. how do you get 2 to 10. times it by five. what ever you do on the denominator you have to do it in the numerator. i multiplied the denominator by 5 so i have to do it to the numerator. 1x5=5. [5/10 x 2/10]

Step 2. Subtract the top numbers (the numerators). Put the answer over the the same denominator as in step 1

Step 3. Simplify the fraction.
