\frac{1\times 3}{2\times 4}-\frac{\frac{5}{2}}{-2}=\frac{1}{4}x
Multiply \frac{1}{2} times \frac{3}{4} by multiplying numerator times numerator and denominator times denominator.
\frac{3}{8}-\frac{\frac{5}{2}}{-2}=\frac{1}{4}x
Do the multiplications in the fraction \frac{1\times 3}{2\times 4}.
\frac{3}{8}-\frac{5}{2\left(-2\right)}=\frac{1}{4}x
Express \frac{\frac{5}{2}}{-2} as a single fraction.
\frac{3}{8}-\frac{5}{-4}=\frac{1}{4}x
Multiply 2 and -2 to get -4.
\frac{3}{8}-\left(-\frac{5}{4}\right)=\frac{1}{4}x
Fraction \frac{5}{-4} can be rewritten as -\frac{5}{4} by extracting the negative sign.
\frac{3}{8}+\frac{5}{4}=\frac{1}{4}x
The opposite of -\frac{5}{4} is \frac{5}{4}.
\frac{3}{8}+\frac{10}{8}=\frac{1}{4}x
Least common multiple of 8 and 4 is 8. Convert \frac{3}{8} and \frac{5}{4} to fractions with denominator 8.
\frac{3+10}{8}=\frac{1}{4}x
Since \frac{3}{8} and \frac{10}{8} have the same denominator, add them by adding their numerators.
\frac{13}{8}=\frac{1}{4}x
Add 3 and 10 to get 13.
\frac{1}{4}x=\frac{13}{8}
Swap sides so that all variable terms are on the left hand side.
x=\frac{13}{8}\times 4
Multiply both sides by 4, the reciprocal of \frac{1}{4}.
x=\frac{13\times 4}{8}
Express \frac{13}{8}\times 4 as a single fraction.
x=\frac{52}{8}
Multiply 13 and 4 to get 52.
x=\frac{13}{2}
Reduce the fraction \frac{52}{8} to lowest terms by extracting and canceling out 4.
