A wasp’s stinger has an average length of 2.67 × 10^−3 meter long. What is this length in decimal notation?

To convert the length to decimal notation, we need to move the decimal point 3 places to the right because the exponent is negative.

2.67 × 10^−3 = 0.00267

Therefore, the length in decimal notation is 0.00267 meters.
