Please solve ._. The "/" means a fraction

 

6+ 4/5b= 9/10b

 

I tried to solve it and I got 6=b. Please tell me if I am correct or wrong.

6+ 4/5b= 9/10b

 

1.

\(6+\frac{4}{5b}=\frac{9}{10b}\)

\(\frac{4}{5b}-\frac{9}{10b} =-6 \)

\(\frac{8-9}{10b} =-6 \)

\(-1=-60b\)

\(b=\frac{1}{60} \)

 

 

2.

\(6+\frac{4}{5}b=\frac{9}{10}b\)

\(\frac{4}{5}b-\frac{9}{10}b=-6 \)

\(\frac{8b-9b}{10}=-6 \)

\(-b=-60\)

\(b=60\)

 

Find out the right result, but take the head and not the computer.

Well lets see:

 

6+ 4/5b = 9/10b

 

6 = 1/10b

 

b = 60

 

Sorry but you are incorrect. Where did u go wrong??
