The tenth digit is the first after the decimal point to the right. And that is 9. Looking at the next digit after it is 5, and it is up to 5 so we increase the 9 to 10.
And of course the 10 would cause an increase to the 8 for it to become 9.
Yes the ones place changed to 9 because when u round numbers you look to the digit to the right of it. If it's 5 or higher you round up. So the digit to the right of 9 being 5 u round up. But 9 rounds up to 10 and then u put the zero in the tenths place and you add one to 8
