John brought 18 pizzas. Micheal bought 12 pizzas. What percent of the total number of pizzas, did Micheal buy ?

Respuesta :

John bought 18, Michael bought 12......for a total of (18 + 12) = 30 pizzas

so Michael bought :  12/30 = 0.4 = 40% of the total number of pizzas
12/(18+12) * 100 = 40% have a great day!
