There are three significant digits in 60.1.
The first 3 significant digits of a number are the first 3 digits starting from the left ignoring any leading zeros. So 31456 = 31500 (3 significant digits) The 5 in the "56" rounds the 4 up.
Three. All nonzero digits are significant and zeros in between significant digits are always significant.

There are three rules that are used when rounding to a desired number of significant digits (figures): 1. All digits that are not zero, are significant 2. In a number that does not have a decimal point, all zeros between two non-zero digits are significant digits 3. In a number that has a decimal point, all zeros after the leftmost non-zero digit are significant Examples: 12345 rounded to 3 significant digits: 12300, or 1.23 x 104 12.345 rounded to 3 significant digits: 12.3, or 1.23 x 101 0.012345 rounded to 3 significant digits: 0.0123, or 1.23 x 10-2 0.012045 rounded to 3 significant digits: 0.0120, or 1.20 x 10-2 In the last example the zero after 2 is significant. That is the reason for keeping it in the result when rewriting it in powers of 10 notation.
9,990 to 3 s.f., or 9,990 (3 s.f.) or 9,990
1,040 to 3 s.f., or 1,040 (3 s.f.) or 1,040.
The digits of a value which can be used with accuracy with other values. ie- you have two measurements, 13.6mg and 15.716mg. The most digits you can use are 3, because 13.6 has an accuracy of 3 digits. If you used 5 digits, accuracy would be limited because you do not know/have the 4th and 5th digits of the first value. When a a significant digit is followed by an exact 5, round to the nearest even digit. ie- 2.03g and 3.045g You have 3 significant digits, so 3.04g is rounded to 3.04g. If it were 3.055g, it would get rounded to 3.06g.
