Answer:
[tex]b=2\frac{2}{5}[/tex]
Step-by-step explanation:
we have
[tex]\frac{1}{3}b=\frac{4}{5}[/tex]
solve for b
That means ---> isolate the variable b
Multiply by 3 both sides
[tex]\frac{1}{3}b(3)=\frac{4}{5}(3)[/tex]
simplify
[tex]b=\frac{12}{5}[/tex]
Convert to mixed number
[tex]\frac{12}{5}=\frac{10}{5}+\frac{2}{5}=2\frac{2}{5}[/tex]
