Calculate the Shaded Region: Rectangle Grid Proportion Problem

Question

What is the marked part?

00:00 Find the marked part

00:03 Let's count the colored amount

00:09 Let's put this amount in the numerator

00:13 Now let's count the total number of parts that make up the whole

00:19 Let's put this number in the denominator

00:25 We colored the entire whole, so we'll get 1

00:30 And this is the solution to the question

Let's begin:

Step 1: Upon examination, the diagram divides the rectangle into 7 vertical sections.

Step 2: The entire shaded region spans the full width, essentially covering all sections, so the shaded number is 7.

Step 3: The fraction of the total rectangle that is shaded is $\frac{7}{7}$ .

Step 4: Simplifying, $\frac{7}{7}$ becomes $1$ .

Therefore, the solution is marked by the choice: Answers a + b.
