Your question is really unclear...But I think this is what you mean:100 is 250% of 40
250
250 millimeters equals .000250 kilometers
There are many answers to this question, here are two 50 x 5 = 250 25 x 10 = 250
-250
-50 + 250 (-50) + 250 250 + (-50) 250 - 50 200
if water, 250 Mg = 250 megagrams (i'm not sure that's what you mean) 250 Mg (megagrams) = 250,000,000 ml 250 mg (milligram) = 0.25 ml 250 ug (micrograms) = 0.00025 ml
250 is 60% of 416.67
250% = 2 1⁄2
250 x 1000
2 times 125 = 250
250
