By the way the question is worded, I would say you undo addition by subtraction. I hope this helped!
Two equivalent fractions to represent the part of the migration a monarch butterfly can complete in 1 week is
or
.
<h3>What is a fraction?</h3>
A fraction is a mathematical expression that shows the relationship between parts vs total. In a fraction, the part is written first and it is known as the numerator. On the other hand, the total is written below and it is known as the denominator.
<h3>How to write a fraction?</h3>
Here are the steps to write a fraction:
- Find the total.
- Find the part.
- Write the fraction.
Based on this, in the chart, the part of the migration these butterflies can complete in a week are the squares in green, while the total is the total squares. This means the fraction for this situation is:
Moreover, you can simplify this fraction and find an equivalent one by dividing the denominator by the numerator as:

Could you draw a better graph? I can't really see where y is at or what everything is.
Since the side of the square frame is 15x, the area of the frame in whole would be:
(15x)² = 225x²
Now if we subtract out the circle mirror with a radius of 5x, we get:
225x² - πr²
225x² - π(5x)²
225x² - π25x²
We can factor out a 25x² and get:
25x² (9 - π)
