398 and 247.
645 - 151 = 494 494 / 2 = 247 247 + 151 = 398 Which means: 398 + 247 = 645 and 398 - 247 = 151
247 + 398 = 645398 - 247 = 151Therefore the two numbers which add together to make 645 and have a difference of 151 are 247 and 398.

645 - 151 = 494 494 / 2 = 247 247 + 151 = 398 Which means: 398 + 247 = 645 and 398 - 247 = 151
247 + 398 = 645398 - 247 = 151Therefore the two numbers which add together to make 645 and have a difference of 151 are 247 and 398.
Let the two numbers be represented by 'a' and 'b'. Then, a + b = 645 And a - b = 151............adding these two eqations together gives :- 2a = 796 : a = 398..........and b = 645 - 398 = 247 (or b = 398 - 151 = 247).
a + b = 645 a - b = 151 Add: 2a = 796 a= 398, making b = 247
Guess and check used to be called trial and error. If you look at 645 and realize that 400 and 245 differ by 155, you know you're only four away. So you try 398 and 247 and there you are.
no, because range is the difference of the highest limit and lowest limit,therefore 665-655 is equal to 10 and not 645..........
129/200 is 645/1000 in simplest form. Math: 645/1000 -> 129/200
