Step-by-step explanation:
Let the diagonal matrix D with size 2x2 be in the form of
![\left[\begin{array}{cc}a&0\\0&d\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Da%260%5C%5C0%26d%5Cend%7Barray%7D%5Cright%5D)
Then the determinant of matrix D would be
det(D) = a*d - 0*0 = ad
This is the product of the matrix's diagonal numbers
So the theorem is true for 2x2 matrices
Two equivalent fractions to represent the part of the migration a monarch butterfly can complete in 1 week is

.
<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:
