解方程:x:7/10=5/28

x:7/10=5/28 解:28x=5×7/10 28x=7/2 x=7/2÷28 x=7/2×1/28 x=1/8

x:7/10=5/28 x=5/28×7/10 =1/8

5×=28-7 5×=21 ×=21/5

x-4/7=5/28 x=5/28+4/7 x=5/28+16/28 x=21/28 x=3/4

x减七分之五x等于28 解:2/7x=28 x=28*7/2 x=98

(35/7十28/5)x35x28 =35/7×35×28十28/5x35x28 =7×28+5×35 =196+175 =371

X=5/4 X=2

14/15×7/10×5/28×16 =14/15×(7/10×5/28)×16 =14/15×(1/8×16) =14/15×2 =28/15

1 x = 2.5 - (8.5 / 5) = 0.6 2 x = 28.5 - 13 = 15.5 3 x = 26.4 / 4 = 6.6 4 x = 19 / (7.5 - 3.5) = 4.75
