Adding FractionsDate: 6/5/96 at 18:23:49 From: Anonymous Subject: Adding fractions Can you help me with this question? 1 1/2 + 4 3/2 ------- Date: 6/14/96 at 9:50:25 From: Doctor Ethan Subject: Re: Adding fractions Hello - First, do you know how to add normal fractions like 1/3 + 4/3 ? When they have the same denominator you just have to add the tops together, so 1/3 + 4/3 = (1+4)/3 = 5/3 Now, with that under our belts we can get to your problem. I always think that the easiest thing to do when you are working with mixed numerals is to first convert them into single fractions. So 1 1/2 = 2/2 + 1/2 = 3/2 and 4 3/2 = 8/2 + 3/2 = 11/2 Now you just need to add 3/2 + 11/2 which by the rule we discussed earlier is (3+11)/2 = 14/2 which reduces to 7. Hope that helps. -Doctor Ethan, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
