Best ResponseYou've already chosen the best response.0A mixed number is like 4 1/2 for example. You change it into a improper fraction. so, you multiply 4x2+1 and that would be 9. Your keep the bottom number and so it is 9/2. you do the same with another mixed fraction. so another could be 2 1/2 and it would be 5/2. Then if the bottom numbers were different, you would have to find the common multiple and multiply the numbers by another number that would get both denominators to get the same multiple. You multiply the top number by the same number you multiplied the bottom number by. In this case, both bottom numbers are the same, so you just do 9/2  5/2 = 4/2. in this case, you can simplify top and bottom by two. So it would be 2/1. 2/1 is the same as 2, so your answer is 2

Best ResponseYou've already chosen the best response.0another ex: 4 1/3 + 3 1/2= 13/3 + 7/2 13/3 + 7/2 is not the same. find the same multiple of the two numbers. LOWEST COMMON MULTIPLE. the lowest would be 6. 13/3 x 6 is 78/6 7/2 x 6 is 42/6 so its 78/6  42/6 =36/6 you can simplify top and bottom by 6. 36/6 / 6 = 6/1 6/1 is the same as 6

Best ResponseYou've already chosen the best response.0example: 3 and 1/2  2 and 3/4 Write each as an improper fraction: 3 and 1/2 is 7/2 2 and 3/4 is 11/4 so the problem is now : (7/2)  (11/4). To subtract, denominators must be the same. So multiply (7/2) by (2/2) so that both fractions have the same denominator. (14/4)  (11/4) =(3/4) If the mixed number is large, like 234 anf 7/8, it might be easier to subtract the whole parts first and then subtract the fractions. If the fraction answer is negative, just combine the whole and fraction parts by subtracting the fraction from the whole part answer.
