It has no precision, since there is no following number.
7
The one farthest to the right of the decimal point (3).
To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the one pound place. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.
A three digit number can be chosen in 9*10*10 = 900ways No. of ways to choose a three digit number without 7 is 8*9*9 = 648 ways probability of picking a three digit number that includes atleast one digit that is 7 is 1- (648/900) = 252/900 = 7/25
A number with more than one digits: that is, an integer greater than 9.
4
3
In this case with 234.896 the last digit, '6' determines the precision since in is the last non-zero digit.
The last digit, 2.
7
7
8
3
Always the last number, so in this example the precision is to hundredths.
The farthest to the right.
If a number is given to the true degree of precision, this is always determined by its last digit - in this case, 6.
