cái này dùng phân số trung gian thôi
-313/370 < -313/371 < -314/371
nên -313/370 < -314/371

Đây bn nhé:
Ta có a/3 = b/8= c/5. Áp dụng tính chất dãy tỉ số bằng nhau ta có:
2a+3b-c/2.3+3.8-5 = 2a+3b-c/6+24-5 = 50/25 = 2
=> a/3 = 2 => a=6
=> b/8 = 2 => b=16
=> c/5 = 2 => c=10
Nhìn ngắn vậy thôi chứ ko sai đâu bn
Chúc bn học tốt^^

\(\dfrac{a}{3}\) = \(\dfrac{b}{8}\) = \(\dfrac{c}{5}\) và 2a + 3b - c = 50
=> \(\dfrac{2a}{6}\) = \(\dfrac{3b}{24}\) = \(\dfrac{c}{5}\) và 2a + 3b - c = 50
Áp dụng tính chất dãy tỉ số bằng nhau ta có:
\(\dfrac{2a}{6}\) = \(\dfrac{3b}{24}\) = \(\dfrac{c}{5}\) = \(\dfrac{2a+3b-c}{6+24-5}\) = \(\dfrac{50}{25}\) = 2
Vậy:
\(\dfrac{2a}{6}=2\) => \(2a=2.6=12\) => \(a=12:2=6\)
\(\dfrac{3b}{24}=2\) => \(3b=2.24=48\) => \(b=48:3=16\)
\(\dfrac{c}{5}=2\) => \(c=2.5=10\)
