4.61乘7分之3-5.39乘(-7分之3)+3乘(-7分之3)要有步骤

4.61乘7分之3-5.39乘(-7分之3)+3乘(-7分之3)要有步骤
4.61乘7分之3-5.39乘(-7分之3)+3乘(-7分之3)要有步骤

4.61乘7分之3-5.39乘(-7分之3)+3乘(-7分之3)要有步骤
.61乘7分之3-5.39乘(-7分之3)+3乘(-7分之3)
4.61*3/7-5.39(-3/7)+3(-3/7)
=3/7(4.61+5.39-3)
=3/7(10-3)
=3/7*7
=3

4.61×7分之3-5.39×(-7分之3)+3×(-7分之3)
=4.61×7分之3+5.39×7分之3-3×7分之3
=7分之3×(4.61+5.39-3)
=7分之3×7
=3

4.61*(3/7)-5.39*(-3/7)+3*(-3/7)
=(4.61+5.39-3)*(3/7)
=7*(3/7)
=3
(负负为正)
