Answer:
a. 27.6
b. 978.3
c. 42.9
d. 9.0.
Step-by-step explanation:
If the hundredth's digit is 5 or greater you round up the tenth's digit.
For example 27.564 There is a 6 in the hundredth's place so we add 1 to the 5 in the tenth's place.
For example Option d the hundredth's is 9 so you add 1 to the 9 in the tenth's place. In this case 8.9 becomes 9.0.
