First, we have to figure out how much cheese we have total. Do this by adding up all of the various cheeses.
[tex] \frac{2}{3} + \frac{4}{3} + \frac{5}{4} \\ \frac{6}{3} + 1 + \frac{1}{4} \\ 3 \frac{1}{4} [/tex]
Now to split the cheeses into sections of 1/4 pound each, we have to divide by 1/4, which is the same as multipling by 4
[tex]3 \frac{1}{4} \times 4 = 12 + 1 = 13[/tex]
13 slices total
