Question

Larre used the visual model to show what fraction of an hour he spent outside. He wants to break the next hour into two times as many sections. Which of these is an equivalent fraction Larry could make by multiplying the numerator and denominator by 2?

Answer 1

First, identify what fracion of an hour Larre spent outside using the model.

Since the square is divided in 4 equal parts, then the denominator of the fraction that Larre wants to represent is 4.

On the other hand, since 2 of those 4 parts are colored, then the numerator of the fraction that Larre wants to represent is 2.

Then, the fraction represented by the visual model is:

$\frac{2}{4}$

To find the answer, find an equivalent fraction by multiplying both the numerator and the denominator by 2:

$\frac{2}{4}=\frac{2\times2}{4\times2}=\frac{4}{8}$

Therefore, an equivalent fraction that can be made by multiplying the numerator and denominator by 2, is:

$\frac{4}{8}$

The correct choice is option C) 4/8.
