Số A, B,C số nào nhỏ nhất
Đúng rồi số B
B kém A 10 lần
B kém C 100 lần
Tổng A+B+ C = 100XB+ B + 10XB = 111XB = 221,778
B= 1,998 sÔ A LÀ 19,98
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

B kém A 10 lần
B kém C 100 lần
A 10 phần ; C 100 phần ; B 1 phần
tổng số phần bằng nhau : 100 + 10 + 1 = 111 phần
số thập phân A là : 221,778 : 111 x 10 = 19,98
=19,98 bạn ạ
đợi mình chút nhé
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.
minh co dap an la19, 98

19,98 nha
cảm ơn
19,98 nha bn !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
bằng 19,98 nha bạn!
chúc bạn học tốt!!!
Nếu chuyển dấu phẩy của A sang trái 1 hàng ta đc số B
=>Vậy B=Ax0,1
Nếu chuyển dấu phẩy của A sang phải 1 hàng ta đc số C
=>Vậy C=Ax10
Bài toán cho:A+B+C=221,778
Hay:A+Ax0,1+Ax10=221,778
Ax(1+0,1+10) =221,778
Ax11,1=221,778
=>A =221,778:11,1
A =19,98
Vậy A là:19,98
Đáp số:...
Vì chuyển dấu phẩy sang bên trái 1 hàng thì giảm 10 lần. Mà nếu chuyển dấu phẩy sang bên phải 1 hàng thì tăng 10 lần. Qua đó, ta có sơ đồ là:
A: 10 phần
B: 1 phần C: 100 phần
Tổng số phần bằng nhau: 10 + 1 +100 = 111 (phần)
Số A là: 221,778 : 111 x 10 = 19,98.
Đ/S : 19,98
Tick cho mik vsss
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 = 100b + b + 10b = 111b = 221,778
Suy ra b = 1,998
Do đó số a là 19,98; số c là: 199,8
Vậy số thập phân a cần tìm là 19,98.
