Naylah has 9 blocks of cheese.how many pizzas can she make if each pizza needs the given amount of cheese, 1/3 block, 1/5 block? show work so i can do more. you.

For the pizza that needs 1/3 of a block you know that with 1 block you can make 3 pizzas so if each block gives you 3 pizzas and you have 9 blocks then you would show 3 x 9 = 27 so you could make 27 pizzas 

for the pizzas that need 1/5 you can make 5 pizzas with 1 block so same thing 
5 x 9 = 45 so 45 pizzas 

Commutative property of multiplication is shown above. This is because no matter how you put them, the answer will still be 140.
