Question

: the mass of an average classroom meter stick is roughly 0. 2 kg.

Answer 1

Using proportions, it is found that it takes $3.5 \times 10^{23}$ meter sticks to equal the mass of the moon.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, one meter stick has a mass of 0.2 kg. How many meter sticks are needed for a mass of $7 \times 10^{22} \text{kg}$? The rule of three is given by:

One meter stick - 0.2 kg

x meter sticks - $7 \times 10^{22} \text{kg}$

Applying cross multiplication:

$0.2x = 7 \times 10^{22}$

$x = \frac{7 \times 10^{22}}{0.2}$

$x = 35 \times 10^{22}$

$x = 3.5 \times 10^{23}$

It takes $3.5 \times 10^{23}$ meter sticks to equal the mass of the moon.
