Answer
First Significant Figure: 0.7 Second Significant Figure: 0.73
Explanation
## Step 1: Identify the First Significant FigureThe first significant figure in the number 0.73 is the 7. This is the digit that we will begin any rounding from. ## Step 2: Identify the Second Significant FigureThe 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. ## Step 3: Round to the First Significant FigureWhen 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.## Step 4: Round to the Second Significant FiguresThe 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.
