十除以八加上三点九六乘以百分之十二点五加上二点零四乘以八分之一简便计算

Answer 1

解：采用分配律
原式=10÷8+3.96x12.5%+2.04x1/8
=10x1/8+3.96x1/8+2.04x1/8
=（10+3.96+2.04）x1/8
=16x1/8
=2

Answer 2

十除以八加上三点九六乘以百分之十二点五加上二点零四乘以八分之一简便计算
10/8+3.96*0.125+2.04*1/8
=10*1/8+3.96*1/8+2.04*1/8
=(10+3.96+2.04)*1/8
=16/8=2

Answer 3

10÷8+3.96×12.5%+2.04×1/8
=10×1/8+3.96×1/8+2.04×1/8
=（10+3.96+2.04）×1/8
=16×1/8
=2

Answer 4

1.875

Answer 5

10÷8+3.96×12.5%+2.04×1/8
=10×1/8+3.96×1/8+2.04×1/8
=（10+3.96+2.04）×1/8
