The decimal that shows the most place value.
Identify the leading digit of the decimal and then round to the leading digit. 0.00693
Ignoring the decimal points, multiply them as if they were whole numbers (ignoring any leading zeros)Put the decimal point into the answer by counting how many digits in total were after the decimal points in the multiplication and put the same number after the decimal point in the answer (inserting leading zeros if necessary).0.009 bx 0.051 → 9 x 51 = 459 (ignoring the leading zeros)There are 3 + 3 = 6 digits after the decimal points (009 and 051), so 6 digits after the decimal point in the answer: 0.000459 (inserting 3 leading zeros)
.9
Move 10 decimal places to the right to get: 7 x 10-10 The exponent is negative since the leading nonzero digit takes place 10 decimal places on the right of the decimal places
0.50 has two significant figures, the 5 and the trailing 0 after the decimal point. The leading zero before the decimal point is not significant.

The leading digit in a number is the digit to the most left. EXAMPLES: 1.09 the leading digit is 1. 298 leading digit 2.
Only to draw attention to the decimal point which might, otherwise, be missed.
A leading digit is the digit/number at the beggining of a decimal number or regular number and is the first number to the left.
Move 10 decimal places to the right to get: 7 x 10-10 The exponent is negative since the leading nonzero digit takes place 10 decimal places on the right of the decimal places
0.50 has two significant figures, the 5 and the trailing 0 after the decimal point. The leading zero before the decimal point is not significant.
three, leading zeros are not significant and trailing zeros are significant if there is a decimal. trailing zeros are not significant if there is no decimal zeros in the middle of numbers are significant
Leading zeros and trailing zeros in numbers that don't have a decimal point.
