Daphne replaced light bulbs in her mothers store.She had 3/4 of a box of light bulbs. She used 1/3 of the bulbs.
a. What fraction of the box of light bulbs was left?
b. How many light bulbs are in a full box? Explain.
Thanks to everyone who helps answer questions it is appreciated.
(1/3) * (3/4) = 3/12 = 1/4 used
4/4 - 1/4 = 3/4 left
To find the number of bulbs in a full box, you need a multiple of 3 and 4 -- which could be
12, 24, 36, 48, etc.
use multiples of 12 to find how many light bulbs are in a whole box.
