Question

paul said that 3 1/5 times 2 3/8 equal 6 3/40 . is paul correct

Answer 1

Paul is incorrect.

$3\dfrac{1}{5}\times2\dfrac{3}{8}=\dfrac{3\cdot5+1}{5}\times\dfrac{2\cdot8+3}{8}=\dfrac{16}{5}\times\dfrac{19}{8}=\dfrac{2}{5}\times\dfrac{19}{1}\\\\=\dfrac{38}{5}=7\dfrac{3}{5}\neq6\dfrac{3}{40}$
