Answer 1

$6\frac{1}{7} -10\frac{3}{14}=\frac{43}{7} -\frac{143}{14}=\frac{43*2}{7*2}-\frac{143}{14}=\frac{86}{14}-\frac{143}{14}=-\frac{57}{14}=-4\frac{1}{14}$

Answer 2

Ответ:

-4 1/14

Объяснение:

6 1/7 - 10 3/14 = 43/7 - 143/14 = (86 - 143)/14 = -57/14 = -4 1/14

Answer 3

To solve the given expression, we need to subtract the second number from the first number.

First, let's convert the mixed numbers into improper fractions:

6 1/7 = (6 * 7 + 1) / 7 = 43/7

10 3/14 = (10 * 14 + 3) / 14 = 143/14

Now, we can subtract these fractions:

43/7 - 143/14

To subtract fractions, we need to find a common denominator. In this case, the least common multiple of 7 and 14 is 14.

We can convert both fractions to have a denominator of 14:

(43/7) * (2/2) = 86/14

143/14

Now, subtracting these fractions:

86/14 - 143/14 = (86 - 143) / 14 = -57/14

Therefore, 6 1/7 - 10 3/14 = -57/14.

Please note that the answer is expressed as a fraction.
