You'd notice that in the 0.8 part that the number 8 is greater than 5, and with rounding, if the number if 5 or over, then you round the decimal place before it to a number higher.
Just look at the end of the number check only 1.08, rounding to the nearest tenth is at the 0 in 1.08, the 8 in 1.08 is the hundredths so you just have to look and read the question correctly to find out that it is 1.1. If you think about it, what is 8 rounded to the nearest ten? it's 10! it's almost the same thing but not entirely the same.
