Question

Se stie ca a supra b= 3 supra 2 .Aflati a) 2a=3b, b) a supra a+b. c) a-b supra b, d) 2a+b supra 3 a + b .

Answer 1

a/b= 3/2      b=2a/3
a) 2a/3b=2/3 ×a/b=2/3×3/2=1  
b) a/(a+b)=a/(a+2a/3)=a/(5a/3)=3a/5a=3/5
c) (a-b)/b=(a-2a/3)/(2a/3)=(a/3)/(2a/3)=a/3×3/2a=1/2
d) (2a+b)/(3a + b) =(2a+2a/3)/(3a+2a/3)=8a/3×3/11a=8/11
