Answer: 130 kg 920 g
Step-by-step explanation:
Given
The weight of the goat is 59 kg 720 g
The combined weight of goat and cow is 190 kg 640 g
Suppose, the weight of the cow is x kg
We know, 1 kg=1000 g
Converting weight into kg
Goat weight
![=59+0.720\\=59.720\ kg](https://tex.z-dn.net/?f=%3D59%2B0.720%5C%5C%3D59.720%5C%20kg)
Total weight
![=190+0.640\\=190.640\ kg](https://tex.z-dn.net/?f=%3D190%2B0.640%5C%5C%3D190.640%5C%20kg)
Then, the cow weight is given by
![\Rightarrow 190.640-59.720\\\Rightarrow 130.920\ kg\ \text{or}\ 130\ kg\ 920\ g](https://tex.z-dn.net/?f=%5CRightarrow%20190.640-59.720%5C%5C%5CRightarrow%20130.920%5C%20kg%5C%20%5Ctext%7Bor%7D%5C%20130%5C%20kg%5C%20920%5C%20g)
The answer is 5.5 because you have to put all of the numbers in numerical order 1 2 3 5 5 6 7 9 9 14 then find the two middle numbers and add them and you get 11. Divide 11 by two and get 5.5.
