Does anyone know the answers to any of those if you know 1 or 2 or 3 of them pls me worth 13 points

23) The decimal place with the greatest digit difference is tenths place 
ex: 1.2
         ^ that number right after the decimal is the tenths place
24) The difference between the heights of Mount Steele and Mount Blackburn is 0.048. I found this by subtracting the height of Mount Steele from the height of Mount Blackburn
25) You order the heights of the mountains by looking to see which mountain has the largest number before the decimal. If they are all the same number, you look to the first number behind the decimal, the tenths place and find what number is the largest, and closest to becoming another whole number. If they are all the same number again, you must look to the hundreths place to find the next largest number of the group. Whichever number has the largest number in this spot, would be the largest, as the mountain with the second largest number in the hundreths place would be the second largest mountain and so forth.
I hope this helps:)
