There are 3 people eating pizza. if each person eats 3/4 of a pizza, how much pizza did they eat altogether?

2¼ pizzas

Step-by-step explanation:

Three people each eat ¾ pizza.

Together they eat 3 × ¾ pizza.

Multiply the numerator by the integer.

3 × ¾ = ⁹/₄

Convert the improper fraction to a mixed number.

⁹/₄ = 2¼

Altogether, they ate 2¼ pizzas.

1)  IF X is the first hat and Y is the second hat , then

X+Y =  $ 75,12, but as Y is twice  more expensive than  X ,  Y = 2X,

X +2X = 75,12 ⇒ 3X = 75,12⇒ X = 75,12/3 = 25,04, then the price of the more expensive hat is

Y = 2* 25,04 =  $50,08
