Math Central is supported by the University of Regina and the Imperial Oil Foundation. This isn't in triangular form, so has no obvious 'weak spot.' But you can (for instance) subtract the second equation from the first to get a second equation in x and z then add this to the third to eliminate z. This gives rise to the linear equation system The three chickens would together, weigh x + y + z or 4.1 + 6.5 + 2 12.6 kgs. I think I might know what you mean, and if so, it's not a ratio problem but a problem in linear algebra. The chickens weigh 4.1 kgs, 6.5 kgs, and 2 kgs. What does 10.6 + 8.5 + 6.1 = 25.2 kg represent in terms of roosters, hens and chicks?

What does one chicken weigh?Ī third solution comes from an observation. Remove the 2.4 kg weight and the scale reads 10.6 - 2.4 = 8.2 kg. Hence, on the scale with the rooster and the hen replace the rooster by an identical hen and a 2.4 kg weight. But the rooster and the hen together weigh 10.6 kg. Thus the rooster weighs 8.5 - 6.1 = 2.4 kg more than the chicken. The rooster and the chick weigh 8.5 kg and the hen and chick weigh 6.1 kg. I am going to use the numeric values in the problem referred to above and refer to the three chickens as a rooster, a hen and a chick with the rooster the heaviest and the chick the lightest. I think this is wonderful problem to give to a group of such students and have them work on a joint solution. This problem can however be presented to a student as soon as he or she learns to do arithmetic with decimals. If your son knows some algebra he can solve it using the algebraic technique used on the web site. I like this problem a lot partly because there are so many ways to solve it.

I think it's a ratio problem, but I am too far removed to formulate a plan to teach him how to solve it. We are to determine the weight of all three together. My son brought home a problem of 3 chickens of different weights listing their weights in different groupings of 2.
