A general rule is to always solve what is in the parenthesis first. Here you are adding 2/5 to 1/5. The answer would be 3/5. Now you are going to take the first part of the equation which is 1 and subtract 3/5. Your answer would be 2/5.

Say for example the parenthesis said (6/15 - 1/5). In this case you would need to find a common denominator which in this case it is 15. You want the denominators to be the same....

1-(2/5 + 1/5)

Lets take 1-(2/5 + 1/5)=x

Therefore, x= 1-(2/5 + 1/5)

In order to solve any Math problem, we need to always keep in mind the BODMAS rule. Therefore, in this problem, we first solve the brackets by taking L.C.M. of the values inside the bracket and adding them up, and so on.

x=1-{(2+1)/5}

x=1-(3/5)

We convert 3/5 into decimal form:

x=1-0.6

x=0.4 or x=2/5

To solve the addition or subtracion of fractions you have to convert all the fractions with the equivalent fractions with the same or equal denominators.

Go for the bracketted expression, where the two terms could be added in the numerator as both has the same or equal denominator 5. You can add the numerator and retain the denominator. So 2/5+1/5 = (2+1)/5 =3/5.

Next step:

1-(2/5+1/5) = 1-3/5.

convert 1 and 3/5 int equivalent fractions of same denominator:

1 = 1/1 = 1*5/(1*5) =5/5. Therefore,

1-3/5 = 5/5-3/5 = (5-3)/5 = 2/5

first add 2/5 + 1/5 which is 3/5.  Then take 1, or 5/5 - 3/5 and the answer is 2/5.

Suppose the probable figure is x

x= 1-(2/5+1/5)

or, x=1-{(2+1)/5}

or, x=1-3/5

or, x= (5-3)/5

or, x=2/5

So, the answer is 2/5. (Ans.)
