The representation of the equation given in the task content; 2/5 v + 3/4 = 2/3x² as a s sentence is; The sum of Two-fifths of a number, v and quarters is equal to two-thirds of the square of the number x.
<h3>What is the representation of the equation as given in the task content?</h3>
It follows from the convention that the following fractions can be named as follows;
- 2/5 means two-fifths.
- 3/4 means three-quarters.
- 2/3 means two-thirds.
Hence, it follows from the iterations above and how they relate to the equation given in the task content that the representation is; The sum of Two-fifths of a number, v and quarters is equal to two-thirds of the square of the number x.
