How To Add Fractions In 3 Easy Steps вђ Mashup Math Adding fractions. a fraction like 3 4 says we have 3 out of the 4 parts the whole is divided into. to add fractions there are three simple steps: step 1: make sure the bottom numbers (the denominators) are the same. step 2: add the top numbers (the numerators), put that answer over the denominator. step 3: simplify the fraction (if possible). Add the 3 numerators together to get a sum of 9 (3 2 4 = 9). 3. put the new numerator on top and leave the denominator as is. take the sum of the numerators and place it on the top of the fraction. when you add like fractions, you don’t add the denominators together.
Adding Fractions вђ Help Me Maths 2. add the fractions : (1) (2) explanation: in this case, the first common multiple that 4 and 7 share is 4 × 7 = 28. multiplying all of the denominators is one way to find a common denominator, but it often won't be the least common denominator. in example 1, we could have multiplied 3 × 6 × 12 = 216, and formed the equivalent fractions:. Step 1: check whether the given fractions are like or unlike fractions. find out whether the denominators are the same. step 2: if the denominator is the same, find the sum of the numerators and place the sum over the common denominator. simplify the final fraction if required. example: 2 5 1 5 = 2 1 5 = 3 5. Step three: add the numerators and find the sum. the final step is to add the numerators and keep the denominator the same: 2 9 4 9 = (2 4) 9 = 6 9. in this case, 6 9 is the correct answer, but this fraction can actually be reduced. since both 6 and 9 are divisible by 3, 6 9 can be reduced to 2 3. final answer: 2 3. Since they have a "common denominator" (the bottom number is the same), we can just add the top numbers together like this: $$ \frac{1}{3} \frac{1}{3}=\frac{2}{3} $$ sadly, all fractions won't be this easy to add. in order to add two fractions, you must first find a common denominator. we can't just add 1 3 to 1 5 because they don't have the.
