1/2

1 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 46

2 1/4

The sum of the numbers given is 31. 1 + 2 + 4 + 8 + ... + 2n = 2n+1 - 1

1 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 12 + 133 + 4 = 195

1 and 2/4 + 3/4 = 2 and 1/4

32

1 1/2 + 8 1/4 = 1 2/4 + 8 1/4 = 9 3/4

7/8 1/2 + 1/4 + 1/8 = 4/8 + 2/8 + 1/8 = 7/8

1/4 + 1/4 = 2/42/4 + 2/8 = 3/4

5 + (10 x 2) + 8 ÷ 4 + 1 = 28

2/4 is equal to 1/2. 1/2 of 8 is 4. 4/8 + 3/8 = 7/8.

The answer to the math problem of 2 plus 2 is 4. And 4 plus 4 is 8 and 8 plus 8 is 16.

1+2+3+4+5+6+7+8+9=37

4/8 can be simplified into 1/2. So 1/2 + 1/2 = 1

7/8 + 2/16 = 7/8 + 1/8 = 8/8 = 1 So 1/4 + 7/8 + 2/16 =1/4 + 1 = 11/4 or 5/4

3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 = 49.6

1/4 + 3/8 = 2/8 + 3/8 = 5/8

8 1/2 + 32 = 40 1/2

1 + 6 + 9 - 8 + 4 - 5 + 2 + 3 = -6

3 over 8 plus -1 over 8 in fractional form is 2 over 8, or 2/8, and can be reduced to 1 over 4, or 1/4.
