小学数学题一道简便运算
必须简便运算的,急等~
16-6*0.54+1.66*3.6+1.66
是16-6
小学数学题一道简便运算必须简便运算的,急等~16-6*0.54+1.66*3.6+1.66是16-6
16-6*0.54+1.66*3.6+1.66=16-6*0.54+1.66*(3.6+1)=16-3.24+7.636=20.396
16-6*0.54+1.66*3.6+1.66
=1.66*(3.6+1+5.4)
=1.66*10
=16.6
16.6*0.54+1.66*3.6+1.66
=1.66*5.4+1.66*3.6+1.66
=1.66*5.4+1.66*3.6+1.66*1
=1.66*(5.4+3.6+1)
=1.66*10
=16.6
题目错了吧》？
16-6还是16.6
16.6*0.54+1.66*3.6+1.66
=1.66*5.4+1.66*3.6+1.66
=1.66*5.4+1.66*3.6+1.66*1
=1.66*(5.4+3.6+1)
=1.66*10
=16.6
原式=16.6*0.54+1.66*3.6+1.66*1
=16.6*0.54+1.66*(3.6+1)
=16.6*0.54+1.66*4.6
=（16.6÷10)*(0.54*10)+1.66*4.6
=1.66*5.4+1.66*4.6
=1.66*(5.4+4.6)
=1.66*10
=16.6
=1.66*5.4+1.66*3.6+1.66*1
=(5.4+3.6+1)*1.66
=10*1.66
=16.6
