A+A+1/2of A + 1/2of 1/2ofA + 1 = 100\n\n-> 2A + A/2 + A/4 = 99\n\nTaking 4 as the LCM\n\n-> 8A + 2A + A = 99*4= 396\n-> 11A = 396\n-> A = 36\nthanx :)

Since you can add (1+1000 =1001) and (2+999 =1001) and you can do this until you reach 500+501=1001, you multiply 1001*500=500500

You could divide two of the 9's by each other to get 1, then combine the other two to get 99, then add them to get 100.

The sum of all the numbers 1 through 100 is 5050. \n\nWhenever you have to add the sum of a numbers in a consecutive interger squence starting with one; find the average of the first and last numbers, (in this case the sum is 101 and average is 50.5). Then multiply the average by the highest number (100). Therefore, 100 * 50.5 =5,050

isn't it to add pairs of mumbers like (1+100) (2+99) (3+98).......(50+51)\n\nall the answers are 101, and there are 50 answers\n\nso 101 x 50 = 5050

the closest i could come was 100 = 95 + 4 + 16/28 + 3/7\n\nokay i done it properley and i'm right. You can rest easy now everyone.\n\nDon't stress - only one answer.
