Answer 1

bằng 2 nha

Answer 2

17/11 + 17/15 - 6/11 + 18/15 

= ( 17/11 + 6/11 )  - ( 7/15 + 8/15 ) 

= 21/11 - 15/15 

= 21/11 -1 

= 10/11

Answer 3

\(\frac{17}{11}+\frac{7}{15}-\frac{6}{11}+\frac{8}{15}\)

= \(\left(\frac{17}{11}-\frac{6}{11}\right)+\left(\frac{7}{15}+\frac{8}{15}\right)\)

= 1 + 1

= 2

Answer 4

bang 2 nha ban

Answer 5

\(\frac{17}{11}+\frac{7}{15}-\frac{6}{11}+\frac{8}{15}\)

\(=\left(\frac{17}{11}-\frac{6}{11}\right)+\left(\frac{7}{15}+\frac{8}{15}\right)\)

\(=\frac{11}{11}+\frac{15}{15}=1+1=2\)

Answer 6

          \(\frac{17}{11}\)\(+\)\(\frac{7}{15}\)\(-\)\(\frac{6}{11}\)\(+\)\(\frac{8}{15}\)

\(=\)\(\left(\frac{17}{11}-\frac{6}{11}\right)\)\(+\)\(\left(\frac{7}{15}+\frac{8}{15}\right)\)

\(=\)\(1+1\)

\(=\)\(2\)

Answer 8

17/11 + 7/15 - 6/11 + 8/15

= 17/11 + 6/11 - 7/15 + 8/15

= 23/11 - 15/15

= 23/11 - 1

= 22/11 = 2
