Question

\(39\dfrac{1}{3}:\dfrac{4}{5}-19\dfrac{1}{3}:\dfrac{4}{5}\)

Answer 1

25

Answer 2

25

Answer 3

\(39\dfrac{1}{3}:\dfrac{4}{5}-19\dfrac{1}{3}:\dfrac{4}{5}\)

\(=\dfrac{118}{3}:\dfrac{4}{5}-\dfrac{58}{3}:\dfrac{4}{5}\)

\(=\left(\dfrac{118}{3}-\dfrac{58}{3}\right):\dfrac{4}{5}\)

\(=20:\dfrac{4}{5}\)

\(=25\)

Answer 4

39\(\dfrac{1}{3}\):\(\dfrac{4}{5}\)-19\(\dfrac{1}{3}\):\(\dfrac{4}{5}\)

=\(\dfrac{118}{3}\):\(\dfrac{4}{5}\)-\(\dfrac{58}{3}\):\(\dfrac{4}{5}\)

=\(\dfrac{295}{6}\)-\(\dfrac{145}{6}\)

=\(\dfrac{89}{6}\)
