why don't you first convert the mixed fraction --> into a fraction then find the same denominators and solve? ^_^

when you do that, you'll get the following form:\[15 \frac{3}{5} + 9 \frac{1}{2} = \frac{78}{5} + \frac{19}{2}\] find the same denominators and use the concept that I have showed you in the previous question :) give it a try now ^_^

ok so i got 10 as the common den. then did 78*2=156 and 19*5=95 so that gives me 156/10 +95/10=251/10. Then i divided 251 by 10 and got 25 with a remainder of 1 and then i came up with 25 1/10 right??

so the remainder is always the top number and the one i divided by is the denominator and the answer is the whole number??
