Question

Calculate the following sum : (3/10) + (6/10).

Answer 1

`(3)/(10)+(6)/(10)` =
`(9)/(10)` = 0.9

Explanation:

Problem to solve:

`(3)/(10)+(6)/(10)`

since, the denominator of the given fractions are equal

Therefore, the number can be directly added as:

`(x)/(a)+(y)/(a)=(x+y)/(a)`

therefore,

`(3)/(10)+(6)/(10)` =
`(3+6)/(10)`

or

=
`(9)/(10)`

or in terms of decimal the answer can be represented as 0.9

Hence,

`(3)/(10)+(6)/(10)` =
`(9)/(10)` = 0.9
