Best ResponseYou've already chosen the best response.0So to do operations on fractions, their denominator (the number on the bottom) has to be the same. We can use one basic property of fractions to help this: \[\frac{x}{x} = 1\]

Best ResponseYou've already chosen the best response.0We can multiply our fraction by something over itself to get it in a new form: \[\frac{1}{8} * \frac{6}{6} = \frac{6}{48}\]

Best ResponseYou've already chosen the best response.0right, so you must find a common multiple for the values of the denominators

Best ResponseYou've already chosen the best response.0now since they have a common denominator, we can do the operation: \[\frac{16}{8} + \frac{6}{48} = \frac{22}{48}\]

Best ResponseYou've already chosen the best response.0you didn't simplify 22/48 it should be 11/24

Best ResponseYou've already chosen the best response.0ya wanna see another way? I use this to get all the fractions out of an equation

Best ResponseYou've already chosen the best response.016/48 + 1/8 = x Multiply everything by the first denominator 16 + 48/8 = 48x then the second denominator (repeat this for every fraction) 128 + 48 = 384x then solve 176/384 = x and simplify 11/24 = x
