I got this because the six right next to the eight is in the hundredths place, and to round you need to look at the number right next to the number in the desired place (the hundredths place), which in this case is the 6. since the 6 is bigger than 5, you add one more to the 6 in the hundredths place, which gives you 0.07.
sorry if I didn't explain very well, but I'm glad to help you out :)
