1. Which statement best defines an equation in mathematics?
A. A mathematical phrase without an equal sign
B. A comparison of two ratios
C. A mathematical statement showing two expressions are equal using an equal sign (=)
D. A variable multiplied by a constant
✅Correct Answer: C
Rationale:
An equation states that two mathematical expressions are equal. The equality is indicated using
the equals sign (=). Equations are used to solve for unknown values.
2. Which of the following correctly defines a mathematical expression?
A. A statement showing two sides are equal
B. A mathematical phrase consisting of numbers, variables, and operations without an equal
sign
C. A relationship between two ratios
D. A variable isolated in an equation
✅Correct Answer: B
Rationale:
An expression represents a quantity but does not include an equality sign. Examples include 5x
+ 7 or 8 + 3.
3. Which of the following is an example of an equation?
A. 4x + 7
B. 3y − 2
C. 8 + 3 = 11
D. 9 ÷ 3
,ESTUDYR
✅Correct Answer: C
Rationale:
An equation must contain two expressions connected by an equals sign. The example 8 + 3 =
11 satisfies this definition.
4. Which of the following is an example of an expression?
A. 9 − 5 = 4
B. x + 7 = 10
C. 8 + 3
D. 4y = 16
✅Correct Answer: C
Rationale:
Expressions contain numbers, variables, or operations without an equal sign.
5. What is the correct strategy when solving an equation for an unknown variable?
A. Add numbers randomly until both sides match
B. Substitute random numbers
C. Multiply both sides by zero
D. Apply the same operation to both sides until the variable is isolated
✅Correct Answer: D
Rationale:
To solve equations, inverse operations must be applied to both sides equally so the variable
becomes isolated.
6. What is a variable in mathematics?
A. A fixed numerical value
B. A number that never changes
C. A symbol representing an unknown or changeable value
D. A number used for multiplication only
, ESTUDYR
✅Correct Answer: C
Rationale:
Variables are usually letters such as x, y, or n used to represent unknown quantities.
7. What is a constant?
A. A number that multiplies a variable
B. A value that varies depending on input
C. A fixed numerical value that does not change
D. A variable without a coefficient
✅Correct Answer: C
Rationale:
Constants remain unchanged in value during calculations.
Example:
In 3x + 7, the number 7 is a constant.
8. In the term 5x, what does the number 5 represent?
A. Variable
B. Exponent
C. Coefficient
D. Constant only
✅Correct Answer: C
Rationale:
A coefficient is the number multiplying the variable.
Example:
5x means 5 × x.
9. When multiplying fractions, which procedure is correct?
A. Add denominators and subtract numerators
B. Multiply denominators only
