Answer:
[tex]Fraction = \frac{20}{43}[/tex]
Explanation:
Given
[tex]Cars = 23[/tex]
[tex]Planes = 43[/tex]
Required
Fraction of his age where he sold cars.
So, first we need to calculate the duration which he sold cars.
[tex]Duration = 43 - 23[/tex]
[tex]Duration = 20[/tex]
This means that he sold cars for 20 years.
To solve further, we'll assume that his current age is 43.
So, the fraction of his age is:
[tex]Fraction = \frac{Duration}{Current\ Age}[/tex]
Substitute values for Duration and Current Age
[tex]Fraction = \frac{20}{43}[/tex]
