That means that $\displaystyle \frac{1}{4}$ of a brick weighs $\displaystyle \frac{3}{4}$ of a pound.

so, $\displaystyle 4\times\frac{3}{4}=3 \ pounds$ - Dec 2nd 2009, 05:37 AMSoroban

Can you visualize the problem?

Code:

*-------* *----* *---*

| B | = | ¾B | + | ¾ |

*-------* *----* *---*

Solve the equation: .$\displaystyle B \;=\;\tfrac{3}{4}B + \tfrac{3}{4}$
