Amy dog weighs 15 kg more than zacks dog

Given that The weight of zacks dog to the weight of amys dog is 6:9

weight of zacks dog : weight of amys dog = 6 : 9

$\frac{\text { weight of zacks dog }}{\text { weight of amys dog }}=(6)/(9)$

Let "6a" be the weight of zack dog

Let "9a" be the weight of amy dog

Also given that zacks dog weight is 30 kg

zacks dog weight = 30 kg

6a = 30

a = 5

Thus the weight of zacks dogs = 6a = 6(5) = 30 kg

weight of amy dog = 9a = 9(5) = 45

To find out how much more amy dog weigh, we have to find difference between weight of amy dog and zack dog

amy dog weigh more = weight of amy dog - weight of zacks dog

amy dog weigh more = 45 - 30 = 15

Thus amy dog weighs 15 kg more than zacks dog
