CBSE Class 6 Maths Important Questions

Below are 10 important questions from Class 6 Maths chapters that are important for preparing well and understanding concepts easily.

1. What are the different types of angles? Describe each type.

Ans: 

• Acute Angle: Less than 90 degrees.

• Right Angle: Exactly 90 degrees.

• Obtuse Angle: Greater than 90 degrees but less than 180 degrees.

• Straight Angle: Exactly 180 degrees.

• Reflex Angle: Greater than 180 degrees but less than 360 degrees.

2. How do you find the perimeter of a rectangle? Give an example.

Ans: The perimeter (P) of a rectangle is calculated using the formula: P = 2(length + width).

Example: For a rectangle with length 5 cm and width 3 cm, P = 2(5 + 3) = 2 × 8 = 16 cm.

3. Explain the concept of a fraction. How do you add two fractions with the same denominator?

Ans: 

• A fraction represents a part of a whole, expressed as $\dfrac{a}{b}$, where 'a' is the numerator and 'b' is the denominator.

• To add two fractions with the same denominator, add the numerators and keep the denominator the same. 

• Example: $\dfrac{2}{5} + \dfrac{3}{5} = \dfrac{(2 + 3)}{5} = \dfrac{5}{5} = 1$.

4. What is the difference between a prime number and a composite number? Provide examples.

Ans: 

• A prime number has exactly two distinct positive divisors: 1 and itself (e.g., 2, 3, 5).

• A composite number has more than two positive divisors (e.g., 4, 6, 8).

5. How do you convert a fraction into a decimal? Show with an example.

Ans: To convert a fraction to a decimal, divide the numerator by the denominator.

Example: $\dfrac{3}{4}$ = 3 ÷ 4 = 0.75.

6. What is the area of a square? How do you calculate it? Provide a numerical example.

Ans: The area (A) of a square is calculated using the formula: A = side × side (or A = side²).

Example: If the side of the square is 4 cm, A = 4 × 4 = 16 cm².

7. Explain the order of operations (BODMAS). Why is it important?

Ans: 

• BODMAS stands for Brackets, Orders (i.e., powers and roots), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

• It is important because it ensures that mathematical expressions are solved in a consistent and correct manner.

8. What is a ratio? How do you simplify a ratio? Give an example.

Ans: 

• A ratio compares two quantities, expressed as a:b.

• To simplify a ratio, divide both terms by their greatest common divisor (GCD).

• Example: The ratio 8:12 can be simplified to 2:3 (by dividing both by 4).

9. Describe the properties of even and odd numbers. How can you identify them?

Ans: 

• Even numbers: Divisible by 2 (e.g., 0, 2, 4).

• Odd numbers: Not divisible by 2 (e.g., 1, 3, 5).

• To identify: An even number ends with 0, 2, 4, 6, or 8, while an odd number ends with 1, 3, 5, 7, or 9.

10. How do you represent data using a bar graph? Explain the steps involved.

Ans:

• Collect Data: Gather the data you want to represent.

• Choose Scale: Decide on a scale for the graph.

• Draw Axes: Draw horizontal and vertical axes.

• Label Axes: Label each axis according to the data.

• Draw Bars: For each category, draw a bar whose height corresponds to the data value.

• Title the Graph: Give the graph a title for clarity.
