Using proportions, it is found that it takes [tex]3.5 \times 10^{23}[/tex] 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 [tex]7 \times 10^{22} \text{kg}[/tex]? The rule of three is given by:
One meter stick - 0.2 kg
x meter sticks - [tex]7 \times 10^{22} \text{kg}[/tex]
Applying cross multiplication:
[tex]0.2x = 7 \times 10^{22}[/tex]
[tex]x = \frac{7 \times 10^{22}}{0.2}[/tex]
[tex]x = 35 \times 10^{22}[/tex]
[tex]x = 3.5 \times 10^{23}[/tex]
It takes [tex]3.5 \times 10^{23}[/tex] meter sticks to equal the mass of the moon.
