Answer :
All we need to do is to divide both sides by the
greatest number that those numbers can be divided by. In this case 18
will do the job for both:
18 ÷ 18 = 1
54 ÷ 18 = 3
So 18 : 54 in its lowest term is as much as 1 : 3
18 ÷ 18 = 1
54 ÷ 18 = 3
So 18 : 54 in its lowest term is as much as 1 : 3
