tim phan so co tong tu so va mau so bang 25 , mau so lon hon tu so 7 don vi
tu cua mot phan so nho hon mau cua no la 50 don vi. neu them vao tu 17 don vi , vao mau 2 don vi thi duoc phan so moi bang nghich dao cua phan so ban dau. tim phan so ban dau
tim phan so co tong va tu so va mau so bang 25 , mau so lon hon 7 don vi
tử số là:
25-7:2=9
mẫu số là:
9+7=16
đs:9;16
tử số phân số đó là :
( 25 - 7 ) : 2 = 9
mẫu số phân số đó là :
( 25 + 7 ) : 2 = 16
vậy phân số đó là \(\frac{9}{16}\)
Tử số phân số đó là : ( 25 - 7 ) : 2 = 9
Mẫu số phân số đó là : ( 25 + 7 ) : 2 = 16
Vậy phân số đó là 9/16
Bai 1:Tim tat ca cac phan so bang phan so 34/51 co mau so tu nhien nho hon 13.
Bai 2:Tim va lap cac cap phan so bang nhau ma tu va mau dung 4 trong 5 so:2;4;8;16;32.
tim 1 phan so co mau so hon tu so 45 don vi va bang phan so 3/5
Bạn ơi, sai đề rồi phải là 46 hoặc 44 đơn vị mới đúng chứ!
tim phan so co mau so hon tu so 36 don vi va biet phan so do co gia tri bang 3/5
tim mot phan so biet neu chuyen 1 don vi tu mau so len tu so thi ta duoc phan so co gi tri bang 1 . con neu chuyen 7 don vi tu tu so xuong mau so thi ta duoc phan so moi co gia tri bang 2/3 . Tim phan so do.
tim mot phan so biet mau so hon tu so 52 don vi va biet phan so do co gia tri bang 51 phan 85
51/85 = 3/5
Hiệu số phần bằng nhau là 5-3=2(phần)
Tử số là 52:2x3=78
Mẫu số là 78+52=130
Phân số là 78/130
