Easy Level Worksheet Questions

Part A: Subjective Questions

Note: Write the answers neatly on a sheet and submit them to your school subject teacher.

(1) Write a rational number between 12 and 23.

(2) Find the reciprocal of 58.

(3) Write the additive inverse of −37.

(4) Represent 34 on a number line.

(5) Write any rational number in the form p/q, where p and q are integers and q ≠ 0.

(6) Simplify: 23 + 13

(7) What is the multiplicative identity of rational numbers?

(8) Is zero a rational number? Justify your answer.

(9) Find the value of 79 ÷ 73.

(10) Write any rational number equivalent to −25.

Drag each property or example to its correct category:

(1) Simplify: (23) × (94) and express in lowest terms.

(2) Verify the commutative property: a + b = b + a for a = 1/4, b = 2/5.

LHS =

RHS =

(3) Find the value of: (37 + 27) × (53).

(4) Find the product of multiplicative inverses of 34 and −25.

Test your understanding with these multiple choice questions:

1. The value of 3/4 + (-3/4) is:

(a) 1 (b) 0 (c) 3/2 (d) -3/2

Correct! A number plus its additive inverse equals 0.

2. Evaluate: (2/3) × (4/5 + 1/5)

(a) 1 (b) 2/3 (c) 10/15 (d) 2

Correct! (2/3) × (4/5 + 1/5) = (2/3) × (5/5) = (2/3) × 1 = 2/3.

3. Which of the following is NOT a rational number?

(a) 0 (b) 3/0 (c) -1/2 (d) 2/7

Correct! 3/0 is undefined because division by zero is not allowed.

4. The multiplicative inverse of 1 is:

(a) 1 (b) 0 (c) -1 (d) Not defined

Correct! The multiplicative inverse of 1 is 1 because 1 × 1 = 1.

5. Which of the following satisfies the closure property under subtraction?

(a) Whole numbers (b) Natural numbers (c) Integers (d) None

Correct! Integers are closed under subtraction (subtracting any two integers gives an integer).
