Question

In the following exercises, change to equivalent fractions using the given LCD.  −915 and 512,LCD=48

Elizabeth Witte · Accepted Answer

Calculation:  Since the LCD is already given, find the number to multiply with 16 and 12 to get the LCD which is 84.  The easiest way to find the numbers for 8 and 6 is to divide the LCD (24) with the denominator.  48÷16=3  48÷12=4  In order to have equivalent fractions, multiply both the numerator and denominator of each fraction with the same number.  The number to be used is from the previous step done.  −916⋅33=−2724  and  512⋅44=2048  Simplify the numerators and denominators, we get  −2724 and 2024.  We do not reduce the resulting fractions. If we did, we would get back to our original fractions and lose the common denominator.
