What is 2 1/5+ 1 and 5/6

To add the mixed numbers 2 1/5 and 1 5/6, we need to first convert both numbers to improper fractions.

2 1/5 = (2 * 5 + 1) / 5 = 11/5

1 5/6 = (1 * 6 + 5) / 6 = 11/6

Now that we have both numbers as improper fractions, we can add them:

11/5 + 11/6

To add fractions, we need a common denominator. The least common multiple (LCM) of 5 and 6 is 30.

Multiplying the numerators and denominators by the appropriate factors to obtain the common denominator:

(11/5) * (6/6) + (11/6) * (5/5)
= 66/30 + 55/30

Now we can add the fractions with the same denominator:

66/30 + 55/30 = (66 + 55) / 30 = 121/30

Therefore, 2 1/5 + 1 5/6 equals 121/30. It can also be expressed as a mixed number as 4 1/30.
