Question 1
What is the result of simplifying the algebraic fraction 6x over 2x?
- A) 3 because the x terms cancel out
- B) 4 because the x terms cancel out
- C) 2 because the x terms cancel out
- D) 5 because the x terms cancel out
Show answer
Answer: 3 because the x terms cancel out
The correct answer is 3 because the x terms cancel out. By dividing 6 by 2, you obtain 3, and since x divided by x equals 1, the variable term is eliminated from the expression.

Question 2
What is the value of 5 over x plus 2 over x?
- A) 7 over x as you add numerators
- B) 3 over x as you add numerators
- C) 7 over 2x as you add numerators
- D) 3 over 2x as you add numerators
Show answer
Answer: 7 over x as you add numerators
The correct answer is 7 over x as you add numerators. When denominators are identical, you simply combine the numerators while keeping the denominator unchanged.

Question 3
What is the simplified form of 10y squared divided by 5y?
Show answer
Answer: 2y
The correct answer is 2y. Dividing 10 by 5 gives 2, and applying index laws, y squared divided by y to the power of 1 results in y to the power of 1.
