Question

Решите (6 5/6 - 2 1/2):13

Answer 1

(6 5/6 - 2 1/2) : 13 = 1/3

1) 6 5/6 - 2 1/2 = 6 5/6 - 2 3/6 = 4 2/6 = 4 1/3

2) 4 1/3 : 13 = 13/3 : 13/1 = 13*1/3*13 = 1/3

Ответ: 1/3

Answer 2

$(6 \frac{5}{6} - 2 \frac{1}{2} ) \div 13 = ( \frac{41}{6} - \frac{5}{2} )* \frac{1}{13} = \frac{13}{3} * \frac{1}{13} = \frac{1}{3}$

Answer 3

First, we need to convert the mixed numbers to improper fractions:

• 6 5/6 = (6 * 6 + 5)/6 = 41/6
• 2 1/2 = (2 * 2 + 1)/2 = 5/2

So the expression becomes:

(41/6 - 5/2) / 13

To simplify the expression, we need to find a common denominator for the two fractions in the numerator:

• 41/6 = (41 * 2)/(6 * 2) = 82/12
• 5/2 = (5 * 6)/(2 * 6) = 30/12

Now the expression becomes:

(82/12 - 30/12) / 13

Simplifying the numerator, we get:

52/12 / 13

To divide by a fraction, we invert and multiply:

52/12 * 1/13 = 52/156 = 13/39

Therefore, the final answer is:

(6 5/6 - 2 1/2) / 13 = 13/39.
