math help.

hey fellas i'm trying to help my son with his homework. i was never really good at math. can anybody chime in the question. thank you much.

At lunch 3 1/4 small pizzas were equally devided into 4 people one person eats 1/4 of what he was given how much of a whole pizza did that person eat

 

Um whattt..

What grade is he in?

 

this is 6th grade math.

 

3 1/4 converts to (3 * 4 + 1) / 4 = 13/4 pizzas total
13/4 pizzas divided by 4 people -> 13/4 * 1/4 = 13/16 (each person gets this much pizza)
13/16 divided by 4 (person ate one quarter of what they were given) -> 13/16 * 1/4 = 13/64 of a whole pizza
Gotta love questions like this which confuse the hell out of the kids when they're just trying to learn the concepts. They're doing this in California too.

 

3.25/4=.8125*.25=.2031

20% or 1/5. He should have eaten more.

 

Answer is 13/64th of a pizza (pretty goofy slicing to make that a likely outcome, btw).

1/4 * 3 1/4 = 1/4 * (12 +1)/4 = 1/4 * 13/4 = 13/16 of a pizza is what each person got. 1/4 * 13/16 = 13/64

 

Holy Shit..well I guess I have this to look forward to.

 

Why did 4 people order 3 1/4 pizzas ?

 

thanks for the explanation bud. now makes much more sense.

 

Maybe they're Canadian?

 

maybe they didn't have enough money? who the hell knows

 

Must be a metric to imperial pizza measurement conversion

 

Why would they order 3 1/4 small pizzas instead of 1 large pizza?

 

Thats been covered

Metric pizzas

 

"I'd like to order 3-1/4 imperial pizzas please, with extra freedom."

 

5 normal people, 3 Canadians, and 8 Siamese twins order 9.5 pizzas. Half of the Siamese twins eat twice as much as the normal people while the other half each twice as much as the normal people and 3 times as much as the Canadians. How many pizzas does each of the hungrier Siamese twins eat?

 

if you have a 6th grader. good luck

 

Common core ....sheesh

 

Maybe 3/4 off a pie hit the floor wile the delivery guy was wheelin
