Để giải câu hỏi trên, ta thực hiện các bước sau:

a) Tìm x trong phép tính x - 5/6 : 1 1/6 = 0,125

Đầu tiên, chuyển 1 1/6 thành phân số bằng cách tính tổng 1 + 1/6 = 6/6 + 1/6 = 7/6.

Sau đó, thay các giá trị đã biết vào phép tính ban đầu:

x - 5/6 : 7/6 = 0,125

Chuyển phép chia cho thành nhân với nghịch đảo của số chia:

x - 5/6 * 6/7 = 0,125

x - 5/7 = 0,125

x = 0,125 + 5/7

x = 0,125 + 0,714

x = 0,839

Vậy x = 0,839.

b) Tìm x trong phép tính (1 - 2/10 + x + 1/5) : (1 1/3 - 2/3 + 3 1/3) - 1 = 1 1/2

Đầu tiên, chuyển các hỗn số thành phân số: 1 1/3 = 4/3, 3 1/3 = 10/3, 1 1/2 = 3/2.

Thay các giá trị đã biết vào phép tính ban đầu:

(1 - 1/5 + x + 1/5) : (4/3 - 2/3 + 10/3) - 1 = 3/2

(1 + x) : (12/3) - 1 = 3/2

(1 + x) : 4 - 1 = 3/2

(1 + x) : 3 = 3/2

1 + x = 9/2

x = 9/2 - 1

x = 9/2 - 2/2

x = 7/2

Vậy x = 7/2.
