to figure out this, we need to add the fractions she has earned,
remember how to add fractions:
[tex]\frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bd}[/tex]then
Step 1
add the fractions
[tex]\frac{3}{6}+\frac{2}{6}=\frac{3\cdot6+2\cdot6}{6\cdot6}=\frac{18+12}{36}=\frac{30}{36}=\frac{5}{6}[/tex]so, the answer is 5/6
to get 5/6, you have to add 1/6 6 times, so
you have to take 5 boxes
