acxbox22 · Answer

you are just finding the LCM

january123 · Answer

of 9 & 12?

miracrown · Answer

Let’s look at what we have here we are given the numbers 12 and 9
for those, you will need to try and find the LCM, for Least Common Multiple
can you try that?

acxbox22 · Answer

yes of 9 and 12
since they just had both today we can just find our LCM and that will be the number of days where she will have both again
