Yes, you must.
adding fractions r easy math prblems. like 1/4 +1/4 = 1/2.
because fact families are like this 2+2=4,4-2=2 and adding
it is just what it sounds like... you take 2 or more fractions and add them. So 1/2 and 1/2 =2/2 or1
Sum of the fractions = sum of numerators divided by their common denominator. Adding Fractions rule implies to addition of fractions having same denominator and as well as adding fractions with different denominators. So rule for adding fractions having the same denominator is add the numerators and simplify For example : 3/5 + 2/5 + 9/5 = (3 + 2 + 9)/5 [add the numerators] = 14/5
You can just add it like regular ol' addition or change it to a decimal by moving the point 2 places to the left, add it, and change it back to a percent. Adding percents is like adding fractions having 100 as the denominator: 35 percent + 10 percent = 35/100 + 10/100 = 45/100 = 45 percent.
1. change the dissimilar fractions to similar fractions by getting the L.C.D or the least common denominator. 2. add the whole numbers and write down the given denominator. 3. reduce the answer to lowest term if possible.
You just add the top numbers together if the bottoms are the same. Example: 1/2 + 1/2 = 2/2 = 1
You need to change the denominators so they are the same ( by timesing them together) E.g. 1/7 1/2 7x2=14
When you add or subtract fractions with like denominators, you just add or subtract the numerators and put them over the same denominator. For example, 3/5 - 2/5 = (3 - 2)/5 = 1/5
No. Like fractions have the same denominator.

Mixed fractions can't become proper fractions. Mixed fractions are greater than one. You can, however, change a mixed number into an IMPROPER fraction by multiplying the whole number by the denominator and adding the numerator to become the new numerator over the original denominator, for example: 2 3/4 = (2×4+3)/4 = 11/4
