Round the following numbers to 1 decimal place.

a)
27.564
b)
978.299
c)
42.935
d)
8.99

Answer 1

a. 27.6

b. 978.3

c. 42.9

d. 9.0.

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.
