Answer:

I maybe wrong but i think that it is 4 1/30

Explanation:

2 1/5=11/5

1 5/6=11/6

6 and 5 LCM is 30

11/5=66/30

11/6=55/30

66/30+55/30=121/30

121/30=4 1/30

Answer:

4
(1)/(30)

Explanation:

An easy way to add two fractions is by finding the LCM of the fractions, then changing the denominators.

LCM - Lowest Common Multiple - Found by taking the sets of each number's multiples, then finding the first number to appear twice.

Let's find the LCM of 5 and 6 so that we can change the fractions to have equal denominators:

5 - 5, 10, 15, 20, 25, 30

6 - 6, 12, 18, 24, 30, 36

The first number to show up twice is 30, so change the fractions to have denominators of 30.


(1)/(5) ×
(6)/(6) =
(6)/(30)


(5)/(6) ×
(5)/(5) =
(25)/(30)

Now, add the fractions:

2
(6)/(30) + 1
(25)/(30)\\ = 3
(31)/(30) = 4
(1)/(30)
