any multiple of 12
Since 2, 3 and 4 divide exactly into the number of rocks
We are looking for the common multiples of 2, 3 and 4
2 × 3 × 4 = 24 is possible but dividing by 2 gives 12 the lowest common multiple
Any multiple of 12 gives a possible number of rocks.
<span>
9 to 11 = 9:11</span>
<span />If u times 2 you will get 18:22 which is equivalent to 9:11
<span>Next u could do 18:22 times 2 to get another equivalent answer to 9:11 </span>
<span /><span>You could just continue this to get more equivalent answer to 9:11</span>
