There is 20 students in her class.

Ex.

3/10 = size of slice; you can get 3 slices from one pizza.

There are 6 pizzas ... 3x6=18; there will be a remained of 1/10 from each pizza because 3/10 is not an even number. Now u would have (6) 1/10's ... So 1/10+1/10+1/10 = 3/10 and 1/10+1/10+1/10=3/10 ... That makes two more slices for two more students ... 18+2=20 slices for 20 kids in the class! : - )
