小升初计算题计算：2.37除以4减1.37乘以25%=4%乘以25%+2/3乘以30%=解方程：x减15%x=2.043

Answer 1

2.37除以4减1.37乘以25%

=(2.27-1.37)x0.25

=0.25

4%乘以25%+2/3乘以30%

=1+0.2

=1.2

解方程：

x减15%x=2.04

0.85x=2.04

x=2.4

3/5乘以4/3减10%x=0

4/5=0.1x

x=0.8÷0.1

x=8

5x%＋6x%=2.2

0.11x=2.2

x=20

（x+75%）乘以30=36

x+75%=1.2

x=1.2-0.75

x=0.45
