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.

3
Always the last number, so in this example the precision is to hundredths.
If a number is given to the true degree of precision, this is always determined by its last digit - in this case, 6.

Ah, what a lovely number you have there! In 2801.3, the digit that determines its precision is the "3" after the decimal point. That little number tells us how detailed and accurate our measurement is, adding a touch of finesse to our mathematical masterpiece. Just remember, every digit plays a special role in creating the beauty of numbers.
