( 16 phần 7 + -11 phần 3 ) + ( 6 phần 5 + -2 phần ) + 37 phần 15

$Đáp$ $án$ $+$ $Giải$ $thích$ $các$ $bước$ $giải$ $:$

   ( $\dfrac{16}{7}$ + $\dfrac{-11}{3}$ ) + ( $\dfrac{6}{5}$ + $\dfrac{-2}{7}$ ) + $\dfrac{37}{15}$

$=$ $\dfrac{16}{7}$ + $\dfrac{-11}{3}$ + $\dfrac{6}{5}$ + $\dfrac{-2}{7}$ + $\dfrac{37}{15}$

$=$ ( $\dfrac{16}{7}$ + $\dfrac{-2}{7}$ ) + ( $\dfrac{-11}{3}$ + $\dfrac{6}{5}$ + $\dfrac{37}{15}$ )

$=$ $\dfrac{14}{7}$ + ( $\dfrac{-55}{15}$ + $\dfrac{18}{15}$ + $\dfrac{37}{15}$ )

$=$ $\dfrac{14}{7}$ + $\dfrac{0}{15}$

$=$ $2$ $+$ $0$

$=$ $2$
