Answer:
a) 3/5=12/20
b) 5/6=25/30
Explanation:
a.) To find the answer you would first find how much it took to get to 20. 5 times 4 is 20. Then to find the numerator you would do 3 times 4 and that would be 12.
b) To find the answer you would first find how much it took to get to 30. So 30/6 is 5. Then you would divide 25 by 5 and you would get 5.
