Question

解方程 速度加分(1-62.5%)X=十六分之三0.6*五分之四-1.2X=0.4五分之四除以（X-0.45)=三分之八

Answer 1

(1-62.5%)x=3/16

37.5%x=3/16

x=3/16÷37.5%=0.5

0.6×4/5-1.2x=0.4

1.2x=0.48-0.4

1.2x=0.08

x=1/15

4/5÷(x-0.45)=8/3

4/5=8/3×(x-0.45)

4/5=8/3x-8/3×0.45

8/3x=4/5+6/5=2

x=2×3/8=3/4

60×40%+6×9/20+x=60

24+54/20+x=60

x=36-27/10=36-2.7=33.3
