1,25 = 125/100 = 5/4 => số lớn : 5 phần , số bé : 4 phần .
Theo bài ra , ta có sơ đồ :
SL : |----------|----------|----------|----------|----------|
SB : |----------|----------|----------|----------|
tttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt
Gọi số lớn là a , số bé là b . Ta có : a - \(\frac{1}{3}\)b = 253 / a - b x 3 = 25 \(\Rightarrow\)253 - 25 = b x 3 - b = b x 2
Vậy 2 lần số bé là : 253 - 25 = 228
Số bé là : 228 : 2 = 114
Số lớn là : 114 + 253 = 367
Đ/S : 367 .
Số bé x 1,25 = Số lớn
Ta đặt số bé là: A còn số lớn là: B
⇒ A/B = 100/125 = 4/5 (Đổi 1,25 = 125%)
Hiệu của 2 số là 13,86. Suy ra 1 phần sẽ bằng 13,86
Số bé là: 13,86 x 4 = 55,44
Số lớn là: 13,86 x 5 = 69,3
Đ/S:...
