How many significant figures does 10.0 have?

Trailing zeros are significant only if there is a decimal point in the number, for example, 1010000 mm has three significant digits, 1000. mm has four significant digits, 0.010 Pa has two significant digits and 10.0 atm has three significant digits.

How do we divide decimals?

Divide decimals by multiplying both numbers by a factor of 10 so the divisor no longer has a decimal value. Then, use long division to divide as normal. Place the decimal point in the quotient directly above the decimal point in the dividend. Multiply both by 100 to get rid of the decimal part in the divisor.

What are the rules of significant figures?
