Question

1/8+3/8 1 1/8+2 3/8 1 1 /8+2 7/8

Answer 1

$\frac{1}{8} + \frac{3}{8} = \frac{1 + 3}{8} = \frac{4}{8} = \frac{1}{2} \\ \\ 1\frac{1}{8} + 2 \frac{3}{8} = 1 + 2 + \frac{1 + 3}{8} = 3 \frac{4}{8} = 3 \frac{1}{2} \\ \\ 1 \frac{1}{8} + 2 \frac{7}{8} = 1 + 2 + \frac{1 + 7}{8} = 3 + 1 = 4$

Answer 2

To add fractions, you need to have a common denominator. In this case, the common denominator for all the fractions is 8. Let's perform the calculations step by step:

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

1 1/8 + 2 3/8 = (8/8 + 1/8) + (8/8 + 3/8) = 9/8 + 11/8 = 20/8 = 2 4/8 = 2 1/2

1 1/8 + 2 7/8 = (8/8 + 1/8) + (8/8 + 7/8) = 9/8 + 15/8 = 24/8 = 3 0/8 = 3

So, the results are:

1/8 + 3/8 = 1/2 1 1/8 + 2 3/8 = 2 1/2 1 1/8 + 2 7/8 = 3
