Toán (1/3 + 12/67 + 13/41 )+( 79/67 -28/41 ) giúp em với ạ! 10/08/2021 By Charlie (1/3 + 12/67 + 13/41 )+( 79/67 -28/41 ) giúp em với ạ!
@SANGOFFICIAL $\frac{1}{3}$ + $\frac{12}{67}$ + $\frac{13}{41}$ + ( $\frac{79}{67}$ – $\frac{28}{41}$ ) = $\frac{1}{3}$ + $\frac{12}{67}$ + $\frac{13}{41}$ + $\frac{79}{67}$ – $\frac{28}{41}$ ) =(-1)+1 + $\frac{1}{3}$ = $\frac{1}{3}$ Trả lời
( $\frac{1}{3}$ + $\frac{12}{67}$ + $\frac{13}{41}$ )+ ( $\frac{79}{67}$ – $\frac{28}{41}$ ) = $\frac{1}{3}$ + $\frac{12}{67}$ + $\frac{13}{41}$ + $\frac{79}{67}$ – $\frac{28}{41}$ = ( $\frac{12}{67}$ – $\frac{79}{67}$ ) + ($\frac{13}{41}$ + $\frac{28}{41}$ ) + $\frac{1}{3}$ = (-1) + 1 + $\frac{1}{3}$ = 0 + $\frac{1}{3}$ = $\frac{1}{3}$ Trả lời

$\frac{1}{3}$ + $\frac{12}{67}$ + $\frac{13}{41}$ + ( $\frac{79}{67}$ – $\frac{28}{41}$ )
= $\frac{1}{3}$ + $\frac{12}{67}$ + $\frac{13}{41}$ + $\frac{79}{67}$ – $\frac{28}{41}$ )
=(-1)+1 + $\frac{1}{3}$
= $\frac{1}{3}$
( $\frac{1}{3}$ + $\frac{12}{67}$ + $\frac{13}{41}$ )+ ( $\frac{79}{67}$ – $\frac{28}{41}$ )
= $\frac{1}{3}$ + $\frac{12}{67}$ + $\frac{13}{41}$ + $\frac{79}{67}$ – $\frac{28}{41}$
= ( $\frac{12}{67}$ – $\frac{79}{67}$ ) + ($\frac{13}{41}$ + $\frac{28}{41}$ ) + $\frac{1}{3}$
= (-1) + 1 + $\frac{1}{3}$
= 0 + $\frac{1}{3}$
= $\frac{1}{3}$
