Question

13.7x0.25-3.7÷4简便计算？

Answer 1

很高兴为你解答！
方法有多种，下面为其中一种，详细步骤供参考：
13.7×0.25－3.7÷4
=13.7×0.25－3.7÷（100÷25）
=13.7×0.25－3.7÷100×25
=13.7×0.25－3.7×25÷100
=13.7×0.25－3.7×（25÷100）
=13.7×0.25－3.7×0.25
=（13.7－3.7）×0.25
=10×0.25
=2.5

Answer 2

你好，3.7/4可以为3.7*0.25所以原式可以为13.7*0.25-3.7*0.25=（13.7-3.7）*025=10*0.25=2.5

Answer 3

13.7*0.25-3.7/4
=13.7*1/4-3.7*1/4
=1/4*(13.7-3.7)
=1/4*10
=10/4
=2.5

Answer 4

13.7×0.25-3.7÷4
=13.7×0.25-3.7×0.25
=（13.7-3.7）×0.25
=10×0.25
=2.5

Answer 5

13.7×0.25-3.7÷4
=13.7×0.25-3.7×0.25
=（13.7-3.7）×0.25
=10×0.25
=2.5
