What is significant figures ?
Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value The first non-zero digit is where we start counting significant figures. The first non-zero digit of a number is considered the first significant figure when counting significant figures. The second digit is considered the second significant figure, and so on. The decimal point may be followed by a significant figure to the left or right of it.
Given: ([tex]\frac{(174.2 × 23.46)}{162.9 × 10.73}[/tex])
174.2 × 23.46 = 4086.732
162.9 × 10.73 = 1747.917
[tex]\frac{4086.732}{1747.917}[/tex] = 2.338 (approx)
= 2 ( rounding to 1 significant figure )
Hence the rounding to 1 significant figure is 2.
