Question

$(6\frac{2}{5} * 2\frac{11}{12} - 16)*2\frac{1}{4}$

Answer 1

$1) 6\frac{2}{5}\cdot 2\frac{11}{12}=\frac{32}{5} \cdot \frac{35}{12}=\frac{32\cdot 35}{5\cdot 12}=\frac{56}{3}=18\frac{2}{3} \\ \\ 2) 18\frac{2}{3} -16=2\frac{2}{3} \\ \\ 3) 2\frac{2}{3} \cdot 2\frac{1}{4} =\frac{8}{3} \cdot \frac{9}{4}=\frac{8\cdot 9}{3\cdot 4}=6$
