Question

1(целых)2/3+4*(3(целых)3/4-5/6)делить 6(целых)4/11

Answer 1

Ответ: 1) 3 3/4-5/6=3+4,5/6-5/6=3-0,5/6=3-1/12=35/12

2) 4*35/12=35/3.

3)35/3:6 4/11=35/3:70/11=35*11/(3*70)=385/210=1 175/210=1 35/42=1 5/6.

4)  1 2/3+1 5/6=2+(4+5)/6=2+1 1/2=3 1/2.

Answer 2

$displaystyle tt 1frac{2}{3}+4cdotbigg(3frac{3}{4}-frac{5}{6}bigg)div6frac{4}{11}=frac{5}{3}+4cdotbigg(frac{15}{4}-frac{5}{6}bigg)divfrac{70}{11}=\\\ displaystyle tt =frac{5}{3}+4cdotbigg(frac{45}{12}-frac{10}{12}bigg)cdotfrac{11}{70}=frac{5}{3}+4cdotfrac{35}{12}cdotfrac{11}{70}=frac{5}{3}+frac{35}{3}cdotfrac{11}{70}=\\\ displaystyle tt =frac{5}{3}+frac{55}{30}=frac{50}{30}+frac{55}{30}=frac{105}{30}=bold{3,5}$
