Alena collected 7.8 kg of blueberries, 2.6 kg of blackberries, and 3.9 kg of cranberries. Express the ratio in the smallest natural numbers in this order.


r = (Correct answer is: 6/2:3) Wrong answer


a=78 b=26 c=39  78=2313 26=213 39=313 GCD(78,26,39)=13  x=GCD(a,b,c)=GCD(78,26,39)=13  r0=a/x=78/13=6 r1=b/x=26/13=2 r2=c/x=39/13=3 r=6:2:3a=78 \ \\ b=26 \ \\ c=39 \ \\ \ \\ 78=2 \cdot 3 \cdot 13 \ \\ 26=2 \cdot 13 \ \\ 39=3 \cdot 13 \ \\ \text{GCD}(78, 26, 39)=13 \ \\ \ \\ x=GCD(a,b,c)=GCD(78,26,39)=13 \ \\ \ \\ r_{0}=a/x=78/13=6 \ \\ r_{1}=b/x=26/13=2 \ \\ r_{2}=c/x=39/13=3 \ \\ r=6:2:3
