ai nhanh mk k 3 cái
vì nếu chuyển dấu phẩy của nó sang bên trái 1 hàng thì số đó giảm đi 10 là
và: nếu chuyển dấu phẩy của nó sang bên phải 1 hàng thì số đó tăng thêm 10 lần.
ta có sơ đồ: ( bạn tự vẽ nha, số A là 10 phần, số B là 1 phần và số C là 100 phần )
tổng số phần bằng nhau là: 1+10+100=111(phần)
số A là: 221,778 : 111 x 10 = 19,98
đáp số: 19,98.
cho 3 số thập phân a,b,c.Có tổng là 2004,0384.Tìm số a biết rằng nếu chuyển dấu phẩy của a sang bên trái 2 hàng ta được số b,nếu chuyển dấu phẩy của a sang bên phải 2 hàng thì ta được số c.: các bn giải hộ mk nha
Chuyển dấu phẩy của số A sang bên trái hai hàng ta được số B có nghĩa là số A gấp 100 lần số B.
Chuyển dấu phẩy của số A sang bên phải hai hàng ta được số C,có nghĩa là số C gấp 100 lần số A hay gấp 10 000 lần số B.
Gọi số B là một phần thì số A là 100 phần và số C là 10 000 phần .
Tổng số phần bằng nhau là : 10 000 + 100 + 1 = 10 101 ( phần )
Số B là : 2004,0384 : 10 101 = 0,1984
Số A là : 0,1984 x 100 = 19,84
Đáp số: 19,84
tìm 1 số thập phân A biết rằng nếu chuyển dấu phẩy của nó sang bên trái 1 hàng ta được số B chuyển dấu phẩy sang phải 1 hàng ta được số C .Tổng của A,B,C là 221,778
Tìm số thập phân A, biết rằng nếu chuyển dấu phẩy của nó sang bên trái một hàng ta được số B, chuyển dấu phẩy sang phải một hàng ta được số C. Tổng của A,B và C là 221,778

Cho một số thập phân A , biết rằng nếu chuyển dấu phẩy của số A sang bên phải một hàng ta được số B , nếu chuyển dấu phẩy ang bên trái một hàng ta được số C . Tìm số thập phân A , biết tổng của 3 số A, B,C là 241,314. Mong các bạn giúp mình .
Tìm một số thập phân A, biết rằng nếu chuyển dấu phẩy của nó sang bên trái một hàng ta được số B, chuyển dấu phẩy sang phải một hàng ta được số C. Tổng của A, B và C là 221,778.
tìm 1 số thập phân A biiets rằng nếu chuyển dấu phẩy của nó sang bên trái 1 hàng ta được số B. nếu chuyển dấu phẩy của nó sang bên trái 1 hàng ta được số C. tổng của 3 số A, B, C, là 221,778
Tìm một số thập phân A biết rằng nếu chuyển dấu phẩy của nó sang bên trái 1 hàng ta được số B.Nếu chuyển dấu phẩy của nó sang bên phải một hàng ta được số C.Tổng của ba số A,B,C là 221,778.
Ta thấy trong 3 số thì số B là nhỏ nhất
B kém A 10 lần
B kém C 100 lần
Tổng A+B+ C = 100 x B+ B + 10 x B = 111 x B = 221,778
B= 1,998 nên số A là 19,98
số C là: 199,8
tìm 1 số thập phân A biết rằng nếu chuyển dấu phẩy của nó sang bên trái 1 hàng ta được B nếu chuyển dấu phẩy của nó sang bên phải 1 hàng ta được số C, biết A + B + C = 221,778
