Toán x-3/25=-3/5.7/10 x/216=16/18. -1/48 x=3/5-1/7.-4/10 19/10/2021 By Hailey x-3/25=-3/5.7/10 x/216=16/18. -1/48 x=3/5-1/7.-4/10
a) x-3/25=-3/5.7/10 x – 3/25 = 21/50 x = 21/50 + 3/25 x = 21/50 + 6/50 x = 27/50. b) x/216=16/18. -1/48 x / 216 = -1/54 x/ 216 = -4/216 ⇒ x = -4 c) x=3/5-1/7.-4/10 x = 3/5 + 4/70 x = 42/70 + 4/70 x = 46/70 = 23/35 Trả lời
a) x-3/25=-3/5.7/10
x – 3/25 = 21/50
x = 21/50 + 3/25
x = 21/50 + 6/50
x = 27/50.
b) x/216=16/18. -1/48
x / 216 = -1/54
x/ 216 = -4/216
⇒ x = -4
c) x=3/5-1/7.-4/10
x = 3/5 + 4/70
x = 42/70 + 4/70
x = 46/70 = 23/35
