Question

4целых5 11 +(8целых9 11-5целых7 11)-3целых8 11+1целая 3 11

Answer 1

$4frac{5}{11}+(8frac{9}{11}-5frac{7}{11})-3frac{8}{11}+1frac{3}{11}=5frac{2}{11}$

 

1) $8frac{9}{11}-5frac{7}{11}=frac{97}{11}-frac{62}{11}=frac{97-62}{11}=frac{35}{11}=3frac{2}{11}$

 

2) $4frac{5}{11}+3frac{2}{11}=frac{49}{11}+frac{35}{11}=frac{49+35}{11}=frac{84}{11}=7frac{7}{11}$

 

3) $7frac{7}{11}-3frac{8}{11}=frac{84}{11}-frac{41}{11}=frac{84-41}{11}=frac{43}{11}=3frac{10}{11}$

 

4) $3frac{10}{11}+1frac{3}{11}=frac{43}{11}+frac{14}{11}=frac{43+14}{11}=frac{57}{11}=5frac{2}{11}$

Answer 2

4 5/11+(8 9/11-5 7/11)-3 8/11+1 3/11=4 5/11+3 2/11-3 8/11+1 3/11=7 7/11-3 8/11+1 3/11=3 10/11+1 3/11=5 2/11
