The statement that is true is D. There is approximately 11.36 kilograms of dog food in the bag, because 1/2.2 = 11.36/25
To convert between pounds and kilograms, we use the conversion factor of 1 pound = 2.2 kilograms. This means that 1 pound is equal to 2.2 kilograms, and 2 pounds is equal to 4.4 kilograms, and so on.
In this case, we are given that there is 25 pounds of dog food in a bag, and we want to convert this to kilograms. To do this, we can multiply 25 pounds by the conversion factor of 1 pound = 2.2 kilograms.
25 pounds * (1 kilogram / 2.2 pounds) = 25/2.2 = 11.3636363636 kg.
So, there is approximately 11.36 kilograms of dog food in the bag.
The other options are incorrect. In option A, 1/2.2= 55/22 which is not equal to 25 pounds and the same case in option C. In option B the calculation is not correct as well because 1/2.2 = 25/11.36 doesn't make sense.
Therefore, the only true statement is D. There is approximately 11.36 kilograms of dog food in the bag, because 1/2.2 = 11.36/25
