Question

A ladybugs length measures 2 cm express this measurement in meters. explain your thinking. include an Equation with an exponent in your explanation

Answer 1

The measurement $2\text{ centimetre}$ in meters is $\boxed{\bf 0.02\text{\bf\ metre}}$.

Further explanation:

The centimetre and metre are the units of measurement to calculate the length of an object.

“Centi” is first introduced in metric system that means one hundredth of a unit.

Therefore, $1$ meter is $100\text{ cm}$ or we can say a centimetre is one-hundredth of a meter.

It can be mathematically expressed as follows:

$\boxed{1\text{ m}\rightarrow 100\text{ cm}}$

Procedure used:

Conversion from centimetre to metre.

1) First divide the unit (cm) by $100$.

2) Now represent the resultant fraction into decimal form by moving the decimal two times to the left.

Given:

The length of ladybug is $2\text{ cm}$.

Calculation:

Step 1:

The length of ladybug is $2\text{ cm}$.

Use the above procedure to convert $2\text{ cm}$ into meters.

First divide the number $2$ by $100$.

$\boxed{2\text{ cm}=\dfrac{2}{100}\text{ m}}$  

Step 2:

Now follow the second step of the procedure.

The first digit on the right of decimal known as tenths or can say $\frac{1}{100}$.

The second digit on the right of decimal known as hundredth or can say $\frac{1}{100}$.

The resultant fraction $\frac{2}{100}$ can be convert into decimal form as follows:

$\boxed{\dfrac{2}{100}=0.02}$

Here, we shifted the decimal two times to the left in the digit $2$.

Therefore, the unit of $2\text{ cm}$ in meters is $0.02\text{ m}$.    

Thus,  the measurement $2\text{ centimetre}$ in meters is $\boxed{\bf 0.02\text{\bf\ metre}}$.

Answer 2

Answer:

Length of lady bug in meters is:

0.02

Step-by-step explanation:

A ladybugs length measures 2 cm.

We have to express this measurement in meters.

We know that 1 m=100 cm

1 cm= 1/100 m

      =0.01 m

2 cm=2×0.01 m

      =0.02 m

Hence, Length of lady bug in meters is:

0.02
