4 and 100
It's unclear whether you want two numbers that add to a sum or multiply to a product. 25 x 4 = 100 25 + 75 = 100
15
-115
Multiply it by a 100 and so 0.20*100 = 20%
4 and 100
The numbers are 55.5 and 44.5
There are none (as far as i know)
50 + 50
100 + 14 = 114
It's unclear whether you want two numbers that add to a sum or multiply to a product. 25 x 4 = 100 25 + 75 = 100
1 * 100 * 68 * 10
97 and 3
99, 100, and 101
-4 and -25
x^2+25x-100 is not factorable because there are not numbers that when multiplied equal -100 and when added equal 25.
There are infinitely many possible answers. A pair that is easy to remember is 1 and 500500.
