Những câu hỏi liên quan
tìm 1 số thập phân A biết rằng nếu chuyển dấu phảy của nó sang trái 1 hàng ta được số B chuyển dấu phảy của nó sang phải 1 hàng ta được số C.Tổng của A ; B và C là 221,778
Tìm A,biết chuyển dấu phẩy của nó sang phải một hàng ta được B ,sang trái một hàng ta được C và A+B+C=215,895.
dịch sang trái 1 hàng tức là số đó giảm 10 lần, dịch sang phải 1 hàng tức là số đó tăng 10 lần
=> B = A x 10, A = C x 10
B = C x 100
tìm X
C + C x 10 + C x 100 = 215,895
C x ( 1+ 10 + 100 ) = 215,895
C x 111 = 215,895
C = 215,895 : 111
C = 1,945
vậy A là :
1,945 x 10 = 19,45
Đ/S : 19,45

ta có Ax10=B
A/10=C
Vay B - C = 10xA - A/10 = 957.231
100xA - Ạ = 9572.31
99xA = 9572.31
A = 9572.31/99
