Solution Steps

00:00 Find the marked part
00:05 Let's count the colored amount
00:09 Place this amount in the numerator
00:13 Now let's count the number of parts that divide the whole
00:19 Place this number in the denominator
00:22 And this is the solution to the question

Step-by-Step Solution

Let's solve this problem step-by-step:

First, examine the grid and count the total number of sections. Observing the grid, there is a total of 6 columns, each representing equal-sized portions along the grid, as evidenced by vertical lines.

Next, count how many of these sections are colored. The entire portion from the first column to the fourth column is colored. This means we have 4 out of 6 sections that are marked red.

We can then express the colored area as a fraction: 46 \frac{4}{6} .

Answer

46 \frac{4}{6}
