Question

10/7 + 7/5 + 18/7 + 3/5 - 1/3

Answer 1

ta có 10/7 + 7/5 + 18/7 + 3/5 - 1/3

  = (10/7 + 18/7)+(7/5+3/5)-1/3

  =28/7 +10/5 -1/3

 =4+2 -1/3

 =6-1/3

=18/3-1/3=17/3

Answer 2

\(\frac{10}{7}+\frac{7}{5}+\frac{18}{7}+\frac{3}{5}-\frac{1}{3}\)

\(=\frac{17}{3}\)

Answer 3

(10/7+18/7)+(7/5+3/5)-1/3

=4+2-1/3

=6-1/3

18/3-1/3

=17/3
