Question

The Graf family made two pizzas. They ate 1 and 1/8 pizza before watching a movie, and 1/2 pizza more after the movie. What is a reasonable estimate for the amount of pizza left A less than 1B more than 1/2C less than 1/2D more than 1

Answer 1

C. less than 1/2

Step-by-step explanation:

The family made a total of 2 pizzas.

They ate 1 and 1/8 pizza before and 1/2 after the movie.

The total proportion of pizza eaten from the second one will be:

`\begin{gathered} =(1)/(8)+(1)/(2) \\ =(1)/(8)+(4)/(8) \\ =(5)/(8) \end{gathered}`

Therefore, the amount of pizza left will be:

`\begin{gathered} =1-(5)/(8) \\ =(3)/(8) \\ =0.375 \end{gathered}`

Since 0.375 is closer to 1/2 than 1, a reasonable estimate for the amount of pizza left ​is less than 1/2.
