What is the correct number-line representation of (2x-3)/5<1?

Answer and explanation

Correct answer: x<4, open at 4 and shaded left

The governing concept is solving a fractional linear inequality while checking the sign of the denominator. Since 5 is positive, multiplying both sides by 5 preserves the inequality direction: 2x-3<5. Add 3 to obtain 2x<8, then divide by the positive number 2 to get x<4. The strict sign means 4 is not included, so the number line has an open point at 4. All values smaller than 4 satisfy the condition, so shading extends to the left. Therefore option A is correct. Option B wrongly includes 4, while options C and D reverse the solution direction and describe values greater than 4.
