Question

I don't really get it.​

Answer 1

Answer:

6

Step-by-step explanation: lcf~ the shortest amount it takes us to get to the desired number

let's start with 9, we know 9x2=18 so now we go backwards down the number line to see if and of the numbers times another number will equal 18 also

so 8~ we have 8, 16,24~ no 18 so its not 8

now 7~ 7,14,21~no 18 so not 7

6~ 6, 12, 18~yes it took us 3 times to get to 18, but lets see if there is another

5~ 5,10,15,20~no 18 not 5 either

4~ 4,8, 12, 16, 20~ no 18, not 4 either

3~ 3,6,9,12,15,18~ yes but it took us 6 times to get to 18

now 2~ 2,4,6,8,10,12,14,16,18~ yes but it took us 9 times

so the answer would be 6
