Answer:
2/3
Step-by-step explanation:
According to the question, we need to write the fraction 20/30 in its simplest form. So what we do is we try to find a common factor of both 20 and 30. They do have 2 in common, and they have 5 in common - but since both of them end in 0 we conclude that both 20 and 30 are divisible by 10.
So, to simplify the fraction, we divide the top and bottom by 10:
[tex]\sf{\cfrac{20\div10}{30\div10}}=\cfrac{2}{3}}[/tex]
