Wht is 78.852 rounded to the nearest tenth

Tenth is the first number to the right of the decimal.

In this number, 78.852, the 8 AFTER the decimal is the tenths place.

The answer would be 78.9 because when you look at the hundredths place, or the 5, 5 rounds up so the 8 becomes a 9.

Hope this helps! :)
