1 - (3/10 + 2/5)
First, we need to simplify the fraction within the parentheses:
3/10 + 2/5= (31)/(101) + (22)/(52)= 3/10 + 4/10= 7/10
Now substitute back into the original expression:
1 - 7/10= 10/10 - 7/10= 3/10
Therefore, the answer is 3/10.
1 - (3/10 + 2/5)
First, we need to simplify the fraction within the parentheses:

= (31)/(101) + (22)/(52)
= 3/10 + 4/10
= 7/10
Now substitute back into the original expression:
1 - 7/10
= 10/10 - 7/10
= 3/10
Therefore, the answer is 3/10.
