Hi there, would really appreciate some help in understanding why this is the answer to this equation.
Find the value of 2/3 (4+3q) when q = 4/5.
The answer given in the back of the book im working from is 4 4/15.
Now when i type the equation into my calculator i get 26/5.
I have been trying to work out why the answer is 4 4/15 and cant seem to quite get it.
