If (m<6), what happens after multiplying both sides by (4)?

Answer and explanation

Correct answer: (4m<24)

The direct answer is option A, \\(4m<24\\). Begin with \\(m<6\\). Multiplying every part of an inequality by the positive number 4 gives \\(4m<4(6)\\), so \\(4m<24\\). The inequality sign stays in the same direction because 4 is positive. Option A is correct. Option B, \\(4m>24\\), incorrectly reverses the sign; reversal is required only for multiplication by a negative number. Option C, \\(m<24\\), changes the right side but does not multiply the left side, so it is not the result of multiplying both sides by 4. Option D, \\(m>24\\), has both an incorrect sign and incorrect transformation. For example, if m=5, then 5<6 and 20<24, confirming the rule. Positive multiplication keeps the sign; negative multiplication reverses it.
