Answer 1

Ответ:

$1 \frac{5}{8} + 3 \frac{7}{8} = \frac{13}{8} + \frac{31}{8} = \frac{44}{8} = \frac{11}{2} =$

$= 10 \frac{1}{2} = 10.5$

Answer 2

To add the mixed numbers, 1⅝ and 3⅞, we first need to convert them into improper fractions.

1⅝ can be written as (1 * 8 + 5) / 8 = 13 / 8, and 3⅞ can be written as (3 * 8 + 7) / 8 = 31 / 8.

Now, we can add the fractions:

13/8 + 31/8 = (13 + 31) / 8 = 44 / 8.

Since 44 is divisible by 8, we can simplify the fraction further:

44 / 8 = (4 * 11) / (4 * 2) = 11 / 2.

Therefore, 1⅝ + 3⅞ = 11/2 or 5½.
