Question

(4-14/33×1 11/21)×5 5/8=?​

Answer 1

$(4 - \frac{11}{33} \times 1 \frac{11}{21} ) \times 5 \frac{5}{8} =19 \frac{9}{14} \\ 1) \frac{11}{33} \times 1 \frac{11}{21} = \frac{1}{3} \times \frac{32}{21} = \frac{32}{63} \\ 2)4 \frac{32}{63} = 3 \frac{63}{63} - \frac{32}{63} = 3 \frac{31}{63} \\ 3)3 \frac{31}{63} \times 5 \frac{5}{8} = \frac{220}{63} \times \frac{48}{8} = \frac{55 \times 5}{7 \times 2} = \frac{275}{14} = 19 \frac{9}{14}$
