The sum of 1/2 and 5/8 is 1 1/8
There is no sequence of adds or subtracts of 5, 6, 8, 9, and 10 that sum to 1. Check it with this C++ code... for (int i=0; i<32; ++i) { int sum = 0; if (i&1) sum += 5; else sum -= 5; if (i&2) sum += 6; else sum -= 6; if (i&4) sum += 8; else sum -= 8; if (i&8) sum += 9; else sum -= 9; if (i&16) sum += 10; else sum -= 10; cout << i << " " << sum << endl; }
The sum of 7/8 and 3/4 is 1 5/87/8 + 6/8 = 13/8 = 1 and 5/8
8 / (5 + a) Example: if a = 3 then 8 / (5 + 3) = 8 / 8 = 1 / 1 = 1
The sum of 1/2 and 5/8 is 1 1/8
(5-8)+(1-11) 5-8+1-11 6-19 -13
The sum of 5/8 and 1/13 is 73/104
1/8 + 2/4= 1/8 + 4/8 = 5/8 =0.625
The sum of 1/8 and 1/2 is 5/8.
The sum of 3/8 and 1/4 is 5/8.
you need a common denominator, ie the sum 3/4 - 1/8, turn 3/4 into eighths = 6/8, then sum is 6/8 - 1/8 = 5/8
The sum of 5/6 and 3/8 = 1 5/24
