Answer 1

Ответ:

$= \frac{731}{300}$

Answer 2

To add these fractions together, you need to find a common denominator. In this case, the common denominator is 10.

1/5 can be converted to an equivalent fraction with a denominator of 10 by multiplying both the numerator and denominator by 2: 1/5 * 2/2 = 2/10

1 5/6 can be converted to an equivalent fraction with a denominator of 10 by multiplying the whole number part (1) by 10 and then adding the numerator (5): 1 5/6 = 10/6 + 5/6 = 15/6

So now, your expression becomes:

2/10 + 15/6 + 27/10

Next, you can add these fractions together:

2/10 + 15/6 + 27/10 = (2/10 + 27/10) + 15/6

Now that the denominators are the same (10), you can add the numerators:

(2/10 + 27/10) + 15/6 = (29/10) + 15/6

To add these fractions, you need a common denominator. The least common multiple of 10 and 6 is 30. So, let's convert both fractions to have a denominator of 30:

(29/10) * (3/3) = 87/30 (15/6) * (5/5) = 75/30

Now, the expression becomes:

(87/30) + (75/30)

Now, you can add the fractions since they have the same denominator:

(87/30) + (75/30) = (87 + 75) / 30 = 162/30

You can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 6:

(162/30) ÷ (6/6) = (27/5)

So, the sum of the fractions is 27/5.
