If 4 is the product of 8 and b, 4 is the result of the multiplication of 8 and b. Then,
4 = 8b
Which is the same as:
8b = 4
To find b, let's divide both sides by 8:
[tex]\begin{gathered} \frac{8b}{8}=\frac{4}{8} \\ b=\frac{4}{8} \end{gathered}[/tex]
Dividing the numerator and the denominator by 4:
[tex]\begin{gathered} b=\frac{\frac{4}{4}}{\frac{8}{4}} \\ b=\frac{1}{2} \end{gathered}[/tex]Answer:
[tex]b=\frac{1}{2}[/tex]
