Answer:
3/5
Step-by-step explanation:
First, multiply both tops and both bottoms so you have one fraction.
Reduce by dividing top and bottom by the same number.

12/20 becomes 3/5 because:
12÷4 =3
20÷4=5
Top and bottom are divided by same "scale factor", 4.
3 and 5 do not have any common factors other than 1, therefore 3/5 is the lowest term.
