帮我解答数学有理数加减乘除混合运算,
-11×(-43/13)+3×(-43/13)-5×(-43/13)
-1又1/2×6/7-(-6/7)×2又1/2+(-1/2)×6/7

帮我解答数学有理数加减乘除混合运算,-11×(-43/13)+3×(-43/13)-5×(-43/13)-1又1/2×6/7-(-6/7)×2又1/2+(-1/2)×6/7
-11×(-43/13)+3×(-43/13)-5×(-43/13)
=473/13-129/13+215/13
=344/13+215/13
=559/13
=43
-1又1/2×6/7-(-6/7)×2又1/2+(-1/2)×6/7
=6/7X(-3/2+5/2-1/2)
=6/7X1/2
=6/14
