1/4 − 0.5 + 1/2 − 0.25 + 3/5 + 0.4
To add these fractions and decimals, first, let's convert the decimals to fractions:
1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4 = 1/4 - 1/2 + 1/2 - 1/4 + 3/5 + 2/5
Now let's add the fractions together:
1/4 - 1/2 + 1/2 - 1/4 + 3/5 + 2/5 = (1 - 2 + 1 - 1 + 3 + 2)/5
Simplifying the numerator:
(1 - 2 + 1 - 1 + 3 + 2)/5 = 4/5
Therefore, the sum of 1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4 is 4/5.

Apologies for the previous incorrect response. Let's calculate the sum correctly:
1/4 − 0.5 + 1/2 − 0.25 + 3/5 + 0.4
Convert the decimals to fractions:
1/4 − 1/2 + 1/2 − 1/4 + 3/5 + 2/5
Now let's simplify the fractions:
(1-2+1-1+3+2)/5
Combine like terms in the numerator:
4/5
Therefore, the correct answer is:
C) 14-12+12-14+45+25
positive?
Apologies for the confusion. Let's recalculate the sum correctly:
1/4 − 0.5 + 1/2 − 0.25 + 3/5 + 0.4
Convert the decimals to fractions:
1/4 − 1/2 + 1/2 − 1/4 + 3/5 + 2/5
Now let's simplify the fractions:
(1-2+1-1+3+2)/5
Combine like terms in the numerator:
5/5
Simplify the fraction:
1
Therefore, the correct answer is:
E) 1
E ISN'T EVEN AN OPTION
Apologies for the mistake. Let's go through the calculation again:
1/4 − 0.5 + 1/2 − 0.25 + 3/5 + 0.4
Converting the decimals to fractions:
1/4 − 1/2 + 1/2 − 1/4 + 3/5 + 2/5
Now let's simplify the fractions:
(1-2+1-1+3+2)/5
Combine like terms in the numerator:
4/5
Therefore, the correct answer is:
A) 14-12+12-14+35+25
