Fractions are written as the ratio of two integers. 8.4km^2 of her property are covered in trees

<h3>Ratios and proportions</h3>

Fractions are written as the ratio of two integers

Given the following parameters

total area of open field = 21km^2

If 2/5 of Joys cottage property is covered with trees, the amount covered in trees is expressed as:

Amount covered in trees = 2/5 * 21

Amount covered in trees = 42/5

Amount covered in trees  = 8.4km^2

Hence 8.4km^2 of her property are covered in trees

Austin is 69 years younger than Jamie. 3 years ago, Jamie's age was 4 times Austin's age. How old is Austin now?
matrenka [14]

Answer: 26 years old

Step-by-step explanation:

  1. Create an equation with Austin as x and Jamie as x+69 (I just like workin with addition signs more)= 4(x-3)= x+69-3
  2. Simplify the equations --> 4x-12=x+66
  3. Solve the equation: 3x-12=66 --> 3x=78 --> x=26

This is the same as other age problems, just with the extra step of distributing the multiplication.
