Simplify the expression
bearhunter [10]
First we want to simplify the denominator
\frac{1}{4} - \frac{5}{2}

to subtract, we convert 5/2 to have a denominator of 4
\frac{1}{4} - \frac{10}{4}
- \frac{9}{4}

now we can put this back into the original problem
\frac{4}{ - \frac{9}{4} }
this equation can also be read as
4 \div - \frac{9}{4}

when dividing, we flip the right side and switch to multiplication
\frac{4}{1} \times - \frac{4}{9} = - \frac{16}{9}

answer = - \frac{16}{9}
