Answer:
change is 1.30
Step-by-step explanation:
2.60 ÷ 2 = 1.30
3.90 ÷ 3 = 1.30
? ÷ 5 = 1.30
10.40 ÷8 =1.30
?=1.30 × 5 = 6.50
The second place to the right after the decimal is the hundredth, so basically, to round, you cut off the rest of the decimal places afterwards. If the number after the hundredth is at or above 5, you should make the hundredth 1 higher, but if it is 4 or below, you will just leave it as is. In this case, 3.047 rounds to 3.05. There really is not any math work to show, but just the explanation.<span />
