1.3除6.5的商加上3.2与1/8的和，和是多少？
解方程 3x-50*20％=46 3/4*3/5-20％x=1/20 {1+5％}÷x=1/4 x÷{1-8％}=4

Answer 1

6.5÷1.3＋（3.2+1/8）
=5+3.2+0.125
=8.325

3x=46+10
=56/3

0.2x=9/20-1/20
x=8/20 / 0.2
=2

x=1.05÷1/4
=4.2

x=4*0.92
=3.68

Answer 2

1.3/6.5=0.2,0.2+3.2+0.125=3.525
3x=46+10, x=56/3
0.75*0.6-0.2x=0.05x, 0.45=0.15x, x=3
1.05/x=1/4 x=1.05*4=4.2
x=4*0.92=3.68

Answer 3

6.5÷1.3＋（3.2+1/8

6.5÷1.3＋（3.2+1/8）=5+3.2+0.125=8.325
解：3x=46+10 解：0.2x=9/20-1/20 解：x=1.05÷1/4 解：x=4*0.92
x=56/3 x=8/20*5 x=1.05*4 x=3.68
x=2 x=4.2
