To find the sum of the given expression using fractions:

1 over 4 βˆ’ 1 over 2 + 1 over 2 βˆ’ 1 over 4 + 3 over 5 + 2 over 5

First, combine the fractions with the same denominators:

1 over 4 βˆ’ 1 over 4 + 1 over 2 βˆ’ 1 over 2 + 3 over 5 + 2 over 5

This simplifies to:

0 + 0 + 0 + 0 + 3 over 5 + 2 over 5

Finally, combine the remaining fractions:

3 over 5 + 2 over 5 = (3 + 2) over 5 = 5 over 5 = 1

Therefore, the sum of the given expression is 1.

To find the sum of the given expression using fractions:

1 over 4 βˆ’ 0.5 + 1 over 2 βˆ’ 0.25 + 3 over 5 + 0.4

First, convert the decimal numbers to fractions:

0.5 can be written as 1/2
0.25 can be written as 1/4
0.4 can be written as 2/5

Now, rewrite the expression with fractions:

1 over 4 βˆ’ 1 over 2 + 1 over 2 βˆ’ 1 over 4 + 3 over 5 + 2 over 5

Combine the fractions:

(1 over 4 - 1 over 4) + (1 over 2 + 1 over 2) + (3 over 5 + 2 over 5)

Simplify:

0 + 1 + 5 over 5

The sum is 1.

To determine the value of the expression –5.45 + 4.12 –8.66, you simply need to add and subtract these numbers:

-5.45 + 4.12 - 8.66

= (-5.45 + 4.12) - 8.66

= -1.33 - 8.66

= -10.99

Therefore, the value of the expression –5.45 + 4.12 –8.66 is -10.99.

Apologies for the confusion. Let's reevaluate the expression:

-5.45 + 4.12 - 8.66

Combining the numbers, we have:

-9.01 + 4.12

= -4.89

Therefore, the correct choice from the given options is:

D) –4.89
