括号19又1/9加19又1/9除以1/7括号乘以12.5%的简便方法

希望能够帮到你

(1/9+4/7÷5/7)×45/47 =(1/9+4/5)×45/47 =1/9×45/47+4/5×45/47 =5/47+36/47 =41/47

28/19-(1/7÷1/3+9/19) =(28/19-9/19)-3/7 =1-3/7 =4/7

63乘括号-1又4/9加括号-1/7乘以09等于 =63×(-13/9)-1/7×9 =-91-1/7×9 =-637/7-9/7 =-646/7 63乘括号-1又4/9加括号-1/7乘以09等于负7分之646

(3/7×1/41+1/41×2/9)x63 =1/41x(3/7+2/9)x63 =1/41x(3/7x63+2/9x63) =1/41x(27+14) =1/41x41 =1

(1/2-5/9+7/12)×(-36) =1/2×(-36)-5/9×(-36)+7/12×(-36) =-18+20-21 =-19

7/18+括号3/7+1/9括号简便方法计算 =7/18+2/18+3/7 =1/2+3/7 =7/14+6/14 =13/14

答案是1/7。被除数整理得25/9+25/19;除数整理得175/9+175/19.不过,你确定那是除而不是除以吗?很多这种错的。

详细步骤写在纸上了,行家正解
