✔ 最佳答案

1/8 = 3/5 + k
k = 1/8 - 3/5
k = (1 * 5)/(8 * 5) - (3 * 8)/(5 * 8)
k = 5/40 - 24/40
k = -19/40

1/8 = 3/5 + k
k = 1/8 - 3/5
k = 5/40 - 24/40
k = -19/40

Just subtract 3/5 from 1/8 to give you k=-.475 or -19/40. Hope that helps.

k = 1/8 - 3/5 = 5/40 - 24/40 = (5-24) / 40 = -19/40

1/8=3/5+k
k=1/8-3/5
k=(1*5-3*8)/40
k=-19/40
