Answer 1

Ответ:

$\frac{2}{7} +\frac{5}{6} +5\frac{3}{7} +1\frac{1}{6} =\frac{2}{7} +\frac{5}{6} +\frac{15}{7} +\frac{1}{6}=\frac{12+35+90+7}{42} =\frac{144}{42} =\frac{24}{7} =3\frac{3}{7}$ ≈3,42857

Answer 2

To add these fractions and whole numbers together, you can follow these steps:

Step 1: Convert the mixed numbers to improper fractions. Step 2: Find a common denominator. Step 3: Add the fractions. Step 4: Add the whole numbers.

Let's do it step by step:

Step 1: Convert the mixed numbers to improper fractions: 2/7 + 5/6 + 5 3/7 + 1 1/6

2/7 + 5/6 + (75 + 3)/7 + (61 + 1)/6

2/7 + 5/6 + (35 + 3)/7 + (6 + 1)/6

2/7 + 5/6 + 38/7 + 7/6

Step 2: Find a common denominator. In this case, the common denominator for 7 and 6 is 42.

Step 3: Now, we need to rewrite each fraction with a denominator of 42:

(2/7) * (6/6) = 12/42 (5/6) * (7/7) = 35/42 (38/7) * (6/6) = 228/42 (7/6) * (7/7) = 49/42

So, we have:

12/42 + 35/42 + 228/42 + 49/42

Step 4: Now, add the fractions together:

(12/42 + 35/42 + 228/42 + 49/42) = 324/42

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

(324/6) / (42/6) = 54/7

So, the final result is:

2/7 + 5/6 + 5 3/7 + 1 1/6 = 54/7
