Khi bỏ dấu phẩy của 1 số thập phân ta đc số mới gấp 100 lần số cần tìm
số thập phân đó là :
\(\left(2100,68+6654\right):\left(100+1\right)=86,68\)
Vậy số cần tìm là 86,68
chúc bạn học tốt
Ta có : STN + STP = 1994,34
STP X 100 = STN - 748
STN = STP X 100 + 748
STP X 100 + 748 + STP = 1994,34
STP X 101 + 748 = 1994,34
STP X 101 = 1994,34 - 748
STP X 101 = 1246,34
STP = 1246,34 : 101
STP = 12,34
=> Số thập phân đó bằng 12,34
Ta có : STN + STP = 1994,34
STP X 100 = STN - 748
STN = STP X 100 + 748
STP X 100 + 748 + STP = 1994,34
STP X 101 + 748 = 1994,34
STP X 101 = 1994,34 - 748
STP X 101 = 1246,34
STP = 1246,34 : 101
STP = 12,34
Vậy nó là 12,34
số tự nhiên là 2015
số thập phân 19.81
có cần cách làm ko
X+Y=2100.68
and -X+100=6654
giả hpt X=2.14
Y=86.68
ấn vào Đúng 0 sẽ hiên ra cách làm và kết quả
Khi bỏ dấu phẩy của số đó đi ta được 1 số mới gấp 100 lần số phải tìm
Vậy số thập phân đó là :
( 2100,68 + 6654 ) : ( 100 + 1 ) = 86,68
Đáp số : 86,68
86,68 tôi chắc chắn 1000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000%
