Answer:

67.2 and 94.1

Step-by-step explanation:

Let x represent one number and y represent the other

their sum is

x + y = 161.3 and the difference

x - y = 27.9 now add two equations

x + y + x - y = 161.3 + 27.9

2x = 188.2 divide both sides by 2

x = 94.1 to find the other number subtract this from 161.3

y = 161.3 - 94.1

y = 67.2

If you subtract 1.1 from 5.8 you will end up with 4.7
then you subtract 10^7 from 10^8 which will give you 10^1
then you add the seven back which will give you your answer of
4.7 10^8
