Total pounds of candy you received = Pounds of candy received from Grandmother + Pounds of candy received from Sister + Pounds of Candy received from Best Friend
Add them all up to find the total you received.
Total pounds of candy you received = 1/4 + 1/2 + 1/8 = 2/8 + 4/8 + 1/8 = 7/8 Pounds
When changing the denominator of a fraction, always make sure to change the numerator proportionately as well. For 1/4, since you wish to change the denominator to 8 (which is the largest denominator in the group), and since 8 is equal to 4 × 2, the numerator will also have to be multiplied by 2 (I.e. 1 × 2). This will give you 2/8.
