Best ResponseYou've already chosen the best response.2okay, so you have 11 2/3 + 7 5/8, so you were on the right track doing 711 first, but remember that 2/3 is actually negative since it is part of 11 2/3... so 711 is 4... and you need to add 2/3 + 5/8 so to add 2/3 and 5/8 you need to find the fractions least common denominator (LCD) looking at the denominators 3 and 8, we can see that 24 is the smallest number that 3 and 8 are both factors of. so 2/3 == 16/24, and 5/8 == 15/24. now just add 16/24 and 15/24 which == 1/24 and to finish it, add 1/24 to 4 and we get 4 1/2

Best ResponseYou've already chosen the best response.0Ok, so i have to subtract 711(it's subtract because 11 is negative) to get 4 and 2/3+5/8. So it deals with fractions then, thanks. I know how to solve fractions, i just wanted to make sure. Thanks again.
