Negative mixed fraction

When entering, a negative sign in front of the integer applies to the entire fraction.

\(\displaystyle -2\frac{2}{3}\) is interpreted as   \(\displaystyle -\left(2\frac{2}{3}\right)\)


Example: multiply fractions


Fractions are multiplied by multiplying the numerator and denominator.

\(\displaystyle \frac{a}{b}×\frac{c}{d}= \frac{a×c}{b×d}\)

Multiply by

\(\displaystyle 2\frac{2}{3}×1\frac{1}{2}\)

In order to solve the integers, they are multiplied by the denominator and added to the numerator.

\(\displaystyle 2\frac{2}{3}×1\frac{1}{2} = \frac{2×3+2}{3}×\frac{1×2+1}{2}=\frac{8}{3}×\frac{3}{2}\)

Then the numerator and denominator are multiplied and the fraction reduced.

\(\displaystyle \frac{8}{3}×\frac{3}{2}=\frac{24}{6}=\color{blue}{4}\)
