Ralph likes numbers that are perfect squares but not numbers that are one less than a perfect square. Perfect squares are numbers that can be expressed as the product of an integer multiplied by itself (e.g. 25 = 5 x 5, 400 = 20 x 20, 144 = 12 x 12). Numbers that are one less than a perfect square do not fit this pattern (e.g. 24, 300, 145). Ralph's preference seems to be for the neat, symmetric nature of perfect squares.
25,300,144
HCF(300, 144) = 12
The GCF is 12.
144/300 = 0.48 = 48%
144/600=62/300=31/100

Ralph likes numbers that are square numbers.
Ralph only likes squares of numbers. He likes 25 (5 squared), 400 (20 squared), and 144 (12 squared).
Ralph likes squared numbers and doesn't like non-squared. The square of 5 is 25, 20 is 400 and 12 is 144. The numbers 24, 300, and 145 are not square numbers. Of the numbers 10, 50, 124, 200, and 1600, Ralph will like 1600 because 1600 is the square of 40.
Well, isn't that just a happy little riddle! Ralph likes numbers that are perfect squares, like 25, 400, and 144. Since 200 is also a perfect square (200 x 200 = 40,000), that's why Ralph likes it too. Just like painting, sometimes things just fit together perfectly!

John likes numbers that are perfect squares. 400 is 20 squared, 100 is 10 squared, and 3600 is 60 squared. He doesn't like 300, 99, or 3700 because they are not perfect squares. So, there you have it, John has a thing for those perfect squares!

If you mean "how many 3x5-inch cards cover 300 sq. ft": 1 card = 3*5 =15 sq. in. = 15/144 sq. ft. (12x12 = 144 in^2 = 1 ft^2) N cards *15/144 = 300 N = (300*144)/15 = 2880
