Question

Please help explain this to me

Answer 1

You divide 12 and 90 with 2 you can’t divide it anymore because you can’t divide 6 and 45 with the same answer.
I hope you understand a little better

Answer 2

Answer:

2/15  12/90=2/15

both 12 and 90 are multiples of 6 so we divide both of this by 6

so 12 divided by 6 is 2 and 90 divided by 6 is 15

so simpiflied 12/90 is 2/15
