Ivana has 3/4 pound of hamburger meat. She makes 3 hamburger patties. Each party weighs the same amount . How much does each hamburger patty weigh

If she wants to make identical patties, they have to all weight the same amount. Therefore, she must split the 3/4 pounds in three.
So you want to do 3/4 divided by 3 which is the same thing as (3/4) x (1/3)
You multiply the numerators and denominators and get 3/12
You then want to simplify and get 1/4 pounds
