Homework Statement
In a physics problem where V is the volume i have ##\displaystyle~3V-\frac{3}{4}V~##. i get 2 different answers when i calculate.
Homework Equations
$$a(b-c)=ab-ac$$
The Attempt at a Solution
I can:
$$3V-\frac{3}{4}V=3\left( 1-\frac{1}{4} \right)V=3\frac{3}{4}V$$
And if i solve it simply i get ##~\displaystyle \left( 3-\frac{3}{4} \right)V=2\frac{1}{4}V##
