Math Homework Help? (6th year)?
In my book, he said: Give the number of 3 several traps that have been affected by exactly 5 students. What was the first affected by both students 3 and 5? 12 and 20? 72 and 84? 210 and 315? its really confusing for me. Her only 6th grade Connected Mathmatics2, Prime Time Factors and multiple!
210 and 315 both numbers must be divisible (without decimals) both 3 and 5 12 is divisible by 3 but not 5, 20 is divisible by 5 but not 3 72 is divisible by 3 but not 5, 84 is divisible by 3 but not 5 times 210 (3 * 70 5 * 42) and 315 (3 * 103 and 5 * 63) are divisible by 3 and 5 equally.
