Paul's pizzeria sells 45 cheese pizzas and 20 pepperoni pizzas each week.
what is the ratio of cheese pizzas to pepperoni pizzas sold each week by paul's pizzeria?
3: 1
9: 2
9: 4
4: 2

Okay so there are 45 cheese pizzas and 20 pepperoni pizzas
they are asking for the ratio of cheese pizzas to pepperoni pizzas
that would be 45:20
now this needs to be simplified, so divide both numbers by a common factor, which would be 5 in this case...45/5=9 and 20/5=4
so the ratio would be 9:4
