Question

a metade da diferença entre cinco terços e um meio?

Answer 1

$\dfrac{\dfrac{5}{3}-\dfrac{1}{2}}{2}\\\left(\dfrac{5}{3}-\dfrac{1}{2}\right)\cdot \dfrac{1}{2}\\\left(\dfrac{5\cdot 2}{3\cdot 2}-\dfrac{1\cdot 3}{2\cdot 3}\right)\cdot \dfrac{1}{2}\\\left(\dfrac{10}{6}-\dfrac{3}{6}\right)\cdot \dfrac{1}{2}\\\dfrac{10-3}{6}\cdot \dfrac{1}{2}\\\boxed{\bold{\frac{7}{12}}}$
