Answer:
2 [tex]\frac{1}{2}[/tex]pizzas
Step-by-step explanation:
The equation to this question can be written as 5/6 + 5/6 + 5/6 or 5/6 x 3.
To multiply 5/6 by 3, we can set it up as [tex]\frac{5}{6} * \frac{3}{1}[/tex]. Now to multiple, we just multiply straight across. We do 5 * 3 over 6 * 1 to get 15/6. Now, all we have to do is simplify the fraction. 6 goes into 15 two times, so we know they ate 2 pizzas. Now we are left with 3/6. 3/6 can be rewritten as [tex]\frac{1}{2}[/tex]. In total, they ate 2 [tex]\frac{1}{2}[/tex] pizzas.
Hope this helps!
