Question

question 1 of 15
match each expression to the correct number of significant figures.
185.3
0.06
1,760
55 + 7.1

Explanation:

Step1: Determine significant figures for 185.3

Non - zero digits and zeros between non - zero digits are significant. So, 185.3 has 4 significant figures.

Step2: Determine significant figures for 0.06

Leading zeros are not significant. So, 0.06 has 1 significant figure.

Step3: Determine significant figures for 1,760

Trailing zeros in a number without a decimal are ambiguous. But if we assume it's not a measured value with a specific precision, and following the rule of non - zero digits and zeros between non - zero digits, 1,760 has 3 significant figures (1,7,6).

Step4: Calculate \(55 + 7.1\) and find significant figures

\(55+7.1 = 62.1\). For addition, the result should be rounded to the least number of decimal places. 55 has 0 decimal places and 7.1 has 1 decimal place. But for significant figures, non - zero digits are significant. 62.1 has 3 significant figures.

Answer:

185.3 → 4; 0.06 → 1; 1,760 → 3; \(55 + 7.1\) → 3
