Answer:
The answer for a) is 2/5 and the answer for b) is 2/5.
Explanation:
a) 8/20
then divide both numbers with 2 = 4/10.
again divide both numbers by 2 = 2/5.
So, the answer for (a) is 2/5.
b) 12/30
Again it can divide by 2 = 6/15.
now, you can divide both numbers with 3 = 2/5.
So, the answer for (b) is also 2/5.
