Question

$(3 frac{1}{2} div 4 frac{2}{3} + 4 frac{2}{3} div 3 frac{1}{2} ) times 4 frac{4}{5 }$

Answer 1

(3 1/2 : 4 2/3 + 4 2/3 : 3 1/2) * 4 4/5 = 10,

1) 3 1/2 : 4 2/3 = 7/2 : 14/3 = 7/2 * 3/14 = 3/4,
2) 4 2/3 : 3 1/2 = 14/3 : 7/2 = 14/3 * 2/7 = 4/3 = 1 1/3,
3) 3/4 + 1 1/3 = 3/4 + 4/3 = 9/12 + 16/12 = 25/12 = 2 1/12,
4) 2 1/12 * 4 4/5 = 25/12 * 24/5 = 2 * 5 = 10
