Round 0.037 to 1 significant figure.

When rounding 0.037 to 1 significant figure, the result is 0.04. To round 0.037 to 1 significant figure, we need to identify the first non-zero digit from the left. In this case, the first non-zero digit is 3. Since we are rounding to 1 significant figure, we keep the first non-zero digit and discard all the digits after it. As a result, 0.037 rounded to 1 significant figure is 0.04. Rounding to 1 significant figure means that we are expressing the number to the nearest power of 10. In this case, 0.037 is closer to 0.04 than it is to 0.03, so rounding it to 1 significant figure gives us 0.04. In summary, when rounding 0.037 to 1 significant figure, the result is 0.04. This means that the value of 0.037 is approximated as 0.04 when expressed to 1 significant figure.

To round 0.037 to 1 significant figure, we keep the first non-zero digit (3) and discard the rest. Since 3 is less than 5, we round down. Therefore, 0.037 rounded to 1 significant figure is 0.03. Step 1: Identify the non-zero digit and its position. In 0.037, the first non-zero digit is 3, located in the tenths place (one position to the right of the decimal point). Its position is represented as -1 (negative because it's less than 1). Step 2: Determine the significant digit. The significant digit is simply the identified non-zero digit, which is 3 in this case. Step 3: Round the number based on the significant digit position. Since the significant digit is in the tenths place (-1), we need to round the number to the nearest tenth (whole number in this case). Step 4: Apply rounding rules. If the digit immediately to the right of the significant digit (which is 7 in this case) is 5 or greater, add 1 to the significant digit and discard all other digits to the right. If the digit to the right is less than 5, leave the significant digit as it is and discard all other digits to the right. Step 5: Round and express the result. In this case, 7 (the digit to the right) is greater than 5. Therefore, we add 1 to the significant digit (3) and discard the trailing 7, resulting in 4. Therefore, 0.037 rounded to 1 significant figure is 0.03.
