Here we have a mathematical phrase, and we want to transform this into an algebraic expression.
We will find that the expression is:
\((2/5) \cdot j^2\)
The phrase is:
"two-fifths of the square of the number j"
First, two-fifths of y is written as
\((2/5) \cdot y\)
The square of a number x is written as:
x^2
Then the whole phrase "two-fifths of the square of the number j" can be written as:
\((2/5) \cdot j^2\)
This is:
(2/5) times j squared.
or just:
\((2/5) \cdot j^2\)
