the fact family is 3 because 3 goes into all of them
s
write three numbers that makes a fact family
3 and 2 then 2 and 1 and 3 and 1
9/2 is not equal to 3 in fact 9/2 is about 4.5
The Least Common Multiple (LCM) for 18 3 6 is 18.
18 / 3 = 6 km/h
6
9
Because 18/6 = 3 and 3 times 6 = 18
3*6=18, 6*3=18, 18/3=6, 18/6=3, 6*0=0, 3*0=3, 1*8=8, 8*1=8
3: 3, 6, 9, ... 6: 6, 12, 18, ... 18: 18, 36, 54, ... The lcm(3, 6, 18) = 18, so the multiples of 18 are common multiples of all of them.
