Answer

First Significant Figure: 0.7 <br />Second Significant Figure: 0.73

Explain

## Step 1: Identify the First Significant Figure<br />The first significant figure in the number 0.73 is the 7. This is the digit that we will begin any rounding from.<br /> <br />## Step 2: Identify the Second Significant Figure<br />The second significant figure in the number 0.73 is the 3. This is the number we'll look at when deciding whether to round up or down.<br /> <br />## Step 3: Round to the First Significant Figure<br />When rounding to 1 significant figure, we only look at the first significant digit, in this case the digit 7 and the next immediate number which is 3. Because 3 is less than 5, we retain the first significant digit as it is and drop the other digits, resulting in 0.7.<br /><br />## Step 4: Round to the Second Significant Figures<br />The term "second significant figure" means we want to keep two digits towards the precision of number. Since the number is already a two-digit number (0.73), no rounding or value changed here.
