Question

Lee needed to make drapes the length from the floor to the top of the window. The wall beneath the window had the height of 2 2/3 feet and the height of just the window measured 2 3/4 feet. How long do the drapes have to be?

Answer 1

So we need to add the 2 lengths together

\[\large 2\frac{2}{3} + 2\frac{3}{4}\]
First change to improper fractions
\[\large \frac{8}{3} + \frac{11}{4}\]
Now find a common denominator
\[\large \frac{32}{12} + \frac{33}{12}\]
Now just add over the common denominator
\[\large \frac{32 + 33}{12} = \frac{65}{12}\]
And finally lets just change that back to a mixed number
\[\large 5\frac{5}{12}\]
