\(=\dfrac{12}{15}-\dfrac{10}{15}=\dfrac{2}{15}\)
\(\dfrac{4}{5}-\dfrac{2}{3}=\dfrac{12-10}{15}=\dfrac{2}{15}\)
\(\dfrac{4}{5}\) - \(\dfrac{2}{3}\) = \(\dfrac{2}{15}\)
\(\dfrac{4}{5}-\dfrac{2}{3}=\dfrac{12}{15}-\dfrac{10}{15}=\dfrac{12-10}{15}=\dfrac{2}{15}\)
=4/5 + (-2/3)=12/15+(-10/15)=2/15
\(\dfrac{4}{5}\) - \(\dfrac{2}{3}\) = \(\dfrac{12}{15}\) - \(\dfrac{10}{15}\) = \(\dfrac{2}{15}\)
