- the denominator is the number of the bottom (memory tip: d is for denominator, d is for down – at the bottom Like with all math, experiencing the concept is the best for learning. Use objects and share them.
- Method 1: aˆ?Write the multiples of both denominators until you find a common multiple. The first method is to simply start writing all the multiples of both denominators, beginning with …
- Build two fractions that have a common denominator. Multiply the denominators of your two original fractions to get the new, common denominator. Create two new fractions by putting your results from Step 1 over this new denominator. Add the fractions from Step 2. Add the numerators and leave the denominator the same. When one denominator is a multiple of the other, you can use a quick trick to
- If you are subtracting fractions with like denominators, you just subtract the top numbers. I remind students that the fractions we add must come from the same size whole. You can't add fractions from a small cake and a large cake together. It must refer to the same size whole. In this scenario, the cake has been cut into 5 pieces. If I take 1/5 and add 2/5, I will get 3/5. You do not change
