Hey!
Here is the equation:
[tex] \frac{j}{3} = 4.5 [/tex]
Switch the equation around and it becomes:
[tex] 4.5 \times 3 = j [/tex]
The sign changes when moved to the other sign. At first it was (÷) and now it's (×).
Multiply 4.5 by 3 to find j
[tex] 4.5 \times 3 = 13.5 [/tex]
That means your answer is 13.5
[tex] \framebox{j = 13.5} [/tex]
