The ratio of 6 yards to 9 feet is 1/2 but I can't see where the missing value is
I think the answer is 41.53 percent. If that isn't the right answer than i'm sorry.
You would do 15 + 17. Which equals 32, and that is the least, then choose a number that is larger than 32.
The answer would be 45.3592 killograms
