A ladybug’s length measure 2cm. Express the measurement in meters. Explain your thinking. Include an equation with an exponent in your explanation.
To convert 2cm to meters, we need to divide the length by 100 since there are 100 centimeters in 1 meter.
So, 2cm ÷ 100 = 0.02 meters.
To express this conversion using an exponent, we can write it as:
2cm = 2 × 10^(-2) meters.
Here, the exponent -2 represents the division by 100, because each time we move the decimal point two places to the left, we divide the value by 100.
To express the length of a ladybug, which measures 2cm, in meters, we need to convert centimeters to meters since meters are a larger unit of measurement.
There are 100 centimeters (cm) in 1 meter (m). Therefore, we can use the conversion factor of 1m/100cm to convert centimeters to meters.
Given that the ladybug's length is 2cm, we can express this measurement in meters as:
2cm * (1m/100cm).
Simplifying this expression, we can cancel out the cm units:
2 * 1m / 100.
This simplifies to:
2/100m.
or
0.02m.
So, the length of the ladybug is 0.02 meters.
