Step-by-step solutions included
Exercise #1

What is the marked part?

Step-by-Step Solution

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 77 \frac{7}{7} .

Step 4: Simplifying, 77 \frac{7}{7} becomes 1 1 .

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

Answer:

Answers a + b

Exercise #2

What is the marked part?

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}

Exercise #3

Write the fraction shown in the picture, in words:

Step-by-Step Solution

Step 1: Count the total sections
The circle is divided into 8 equal sections.
Step 2: Count the shaded sections
There are 6 shaded sections in the diagram.
Step 3: Formulate the fraction
The fraction of the shaded area is 68\frac{6}{8}.
Step 4: Express in words
The fraction 68\frac{6}{8} in words is "six eighths".

Therefore, the solution to the problem is "six eighths".

Answer:

Six eighths

Exercise #4

Write the fraction shown in the drawing, in numbers:

Step-by-Step Solution

The number of parts in the circle represents the denominator of the fraction, and the number of colored parts represents the numerator.

The circle is divided into 12 parts, 6 parts are colored.

612=12 \frac{6}{12}=\frac{1}{2}

Answer:

12 \frac{1}{2}

Video Solution
Exercise #5

Write the fraction shown in the drawing, in numbers:

Step-by-Step Solution

The number of parts in the circle represents the denominator of the fraction, and the number of colored parts represents the numerator.

The circle is divided into 3 parts, 1 part is colored.

Hence:

13 \frac{1}{3}

Answer:

13 \frac{1}{3}

Frequently Asked Questions

What is a denominator in a fraction?

+
The denominator is the bottom number in a fraction that shows how many equal parts make up the whole. For example, in 3/8, the denominator 8 means the whole is divided into 8 equal parts.

How do you find the denominator of a fraction?

+
To find the denominator, look at the bottom number below the fraction bar. In any fraction like 5/7, the denominator is always the number at the bottom (7 in this case).

What does the denominator tell you about fractions?

+
The denominator tells you: 1) How many equal parts the whole is divided into, 2) The size of each part (smaller denominators = larger parts), 3) What type of fraction you're working with (halves, thirds, quarters, etc.).

Can denominators be zero or negative numbers?

+
Denominators cannot be zero because division by zero is undefined in mathematics. Denominators can technically be negative, but in elementary fractions, we typically use positive denominators to represent parts of a whole.

What's the difference between numerator and denominator?

+
The numerator (top number) shows how many parts you have, while the denominator (bottom number) shows how many total parts make up the whole. Think of it as 'parts you have' over 'total parts available'.

How do you write fractions with the same denominator?

+
To write fractions with the same denominator, keep the bottom number the same and change only the numerator. For example, fractions with denominator 4: 1/4, 2/4, 3/4, 5/4, etc.

Why is understanding denominators important for kids?

+
Understanding denominators helps students: visualize parts of a whole, compare fraction sizes, add and subtract fractions, solve real-world problems involving sharing and measurement, and build foundation skills for advanced math.

What are common mistakes students make with denominators?

+
Common mistakes include: confusing numerator and denominator positions, thinking larger denominators mean larger fractions, forgetting that denominators represent the whole, and not understanding that denominators show equal parts, not just any parts.
