Question

You received 1⁄4 pound of candy from your grandmother, 1⁄2 pound of candy from your sister, and 1⁄8 pound of candy from your best friend. How many pounds of candy did you receive?

Answer 1

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.

Hope this helps! :)
