Question

Aflari numerele a, b, c, stiind ca a supra 3 =b supra 5=a supra 6 =c supra 7 si a +b+c=46

Answer 1

cred ca problema e astfel

a/3 = b/5 => b = 5a/3

si

a/6 = c/7 => c = 7a/6

Inlocuim

⁶⁾a + ²⁾5a/3 + 7a/6 = ⁶⁾46

6a + 10a + 7a = 276

23a = 276

a = 276 : 23

a = 12

b = 5×12/3 = 5×4 = 20

c = 7×12/6 = 7×2 = 14
