\frac{a+b}{a}=3\Longrightarrow\frac{a}{a}+\frac{b}{a}=3 \\

1+\frac{b}{a}=3\Longrightarrow\underline{b=2a} \\ \\

\frac{t+a}{a}=5\Longrightarrow\frac{t}{a}+\frac{a}{a}=5 \\

\frac{t}{a}+1=5\Longrightarrow\underline{t=4a} \\ \\

\frac{b}{t}=\frac{2a}{4a}=\boxed{\frac{1}{2}=0.5}

Hope this helps.

Answer: b/t = 1/2  (or) 0.5

Step-by-step explanation:

a+b/ a =3

a+b =  3a

b = 3a-a

b = 2a

t+a/a = 5

t+a = 5a

t = 5a-a

t = 4a

b/t = 2a /4a

     = 1/2
