Answer: b. Every 24 minutes Step-by-step explanation: A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes. The first step is to: Find and list multiples of each time each neon sign blinks. This means, we find the Multiples of 6 and 8 Multiples of 6: 6, 12, 18, 24, 30, 36 Multiples of 8: 8, 16, 24, 32, 40 The first and common multiple of 6 and 8. Therefore, the Least common multiple [LCM(6, 8) ] = 24 Hence, they often blink at the same time every 24 minutes. Therefore, option b.Every 24 minutes is correct.
