Answer:
The answer is A.
Step-by-step explanation
The only thing we need to do is convert 4/5 to a decimal and then add it to one. Remember that 4/5, when both sides of the fraction are multiplied by two, give us 8/10. Remember that 1/10 is equal to 0.1. So all we do is multiply 8 by 0.1. This gives us 0.8. Add that to one, and we get 1.8. So the answer is A.
