The list of two-digit numbers whose digits add up to 10 would be:
19
28
37
46
55
64
73
82
91
Now the numbers have the same digits only reversed and the difference between the two numbers is 18 - the only pair that fits this description is 46 and 64, thus those are the two numbers
A. 8.75
B. 0.72
C. 9.31
D. 23.04
E. 6.98
Step-by-step explanation:
8=1,2,4,8.
12=1,2,3,4,6.
18=1,2,3,6,9.
so 2 is common and lowest in everyone.
