Question

lets prepare for a marathon with some tips about how much to eat and drink each day. build a model and choose an expression to represent each tip. tip one: drink \\(\frac{1}{2}\\) liter of water 4 times each day. each square represents 1 liter. which model shows \\(\frac{1}{2}\\) liter shaded?

Explanation:

Step1: Analyze the first model

The first square (representing 1 liter) is divided into 3 equal parts. The shaded part is 1 out of 3, so the fraction is $\frac{1}{3}$, which is not $\frac{1}{2}$.

Step2: Analyze the second model

The second square (representing 1 liter) is divided into 2 equal parts. The shaded part is 1 out of 2, so the fraction is $\frac{1}{2}$, which matches the required $\frac{1}{2}$ liter shaded.

Answer:

The second model (the one with the square divided into 2 equal parts, with 1 part shaded) shows $\frac{1}{2}$ liter shaded.
