Question

Sum of 1/3, 1/5 and 1/6 in simplest form

Answer 1

7/10

Explanation:

1/3 + 1/5 = 8/15

8/15 + 1/6 = 21/30

21/30 = 7/10

Answer 2

`{\huge\red{\fbox{{࿐αɴѕωєя࿐}}}}`

`(1)/(3) + (1)/(5) + (1)/(6)`

First you need to find the LCM of the denominators.

LCM of 3, 5, 6 = 30

`(1)/(3) * (10)/(10) \\ = (10)/(30)`

`(1)/(5) * (6)/(6) \\ = (6)/(30)`

`(1)/(6) * (5)/(5) \\ = (5)/(30)`

Now, since the denominators are equal you can easily add them.

`(10)/(30) + (6)/(30) + (5)/(30) \\ = (10 + 6 + 5)/(30) \\ = (21)/(30) \\ = (7)/(10) \\ = 0.7`

✏ Answer = 7/10 in fraction form & 0.7 in decimal form.
