Question

Scale factor from a to b = 5 : 6

Answer 1

12.) To get to 6 to 24, you multiply it by 4. So, in order to get 5 to a certain number, you must also multiply it by 4.
5 times 4 is 20. So, 20 would be A.
14.) To get 3 to 15, you multiply it by 5. So, in order to get 1 to a certain number, you must also multiply it by 5.
1 times 5 is 5. So, 5 would be A.
