1. Move the decimal point:

* Start with 0.0247

* Move the decimal point to the right until you have a number between 1 and 10. In this case, we move it two places to the right: 2.47

2. Count the moves:

* We moved the decimal point two places to the right.

3. Combine the number and exponent:

* The number is 2.47

* The exponent is -2 (since we moved the decimal right)

Therefore, 0.0247 in scientific notation is 2.47 x 10⁻²
