Question from Cecilia:

if one third of a pole is red, one quarter is white and 15m is black what is the height of the entire pole

Hi Cecilia,

You didn't say so but I assume there are only 3 colors. $\frac13$ of the pole is red and $\frac14$ of the pole is white. What is the sum of $\frac13$ and $\frac{1}{4}?$ What fraction of the pole remains? That fraction of the pole is 15m. What is the height of the pole?
