Question

2 1/6+(-5/6) (/- это дробь)

Answer 1

2 1/6 + (-5/6) = 1 6/6 + 1/6 - 5/6 = 1 7/6 - 5/6 = 1 2/6 = 1 1/3

Answer 2

To add the fractions 2 1/6 and -5/6, we first need to convert the mixed number 2 1/6 into an improper fraction.

To convert the mixed number 2 1/6 to an improper fraction, we multiply the whole number (2) by the denominator of the fraction (6) and add the numerator (1). Then we put the result over the denominator:

2 1/6 = (2 * 6 + 1)/6 = 13/6

Now we can add the fractions:

13/6 + (-5/6)

To add fractions with the same denominator, we simply add their numerators and keep the denominator the same:

(13 + (-5))/6 = 8/6

The resulting fraction is 8/6, which can be simplified further by dividing both the numerator and denominator by their greatest common divisor, which is 2:

8/6 = (8/2)/(6/2) = 4/3

So, the sum of 2 1/6 and -5/6 is 4/3.
