Answer:
C & D
Step-by-step explanation:
For the first one, all you have to do is count how many numbers are behind the decimal point and add them together (1 + 3 = 4) and then you count up the decimal 4 places which would be 0.7416.
For the second one, you divide the days by miles (18/3=6) then you divide the 6 by 72 which would be 12.
Hope this helps!
