Answer 2

in fraction form bot

Answer 3

To express the numerical expression in fraction form:

-5.45 + 4.12 - 8.66 can be written as (-545/100) + (412/100) - (866/100).

Adding the fractions together:

(-545/100) + (412/100) - (866/100) = (-545 + 412 - 866) / 100 = (-999/100).

Answer 4

Evaluate the numerical expression.

1/2− (−3/4)

Answer 5

To evaluate the numerical expression 1/2 - (-3/4), we can rewrite it as adding the opposite:

1/2 + 3/4.

To add fractions, we need a common denominator. The least common denominator for 2 and 4 is 4.

Multiplying the numerator and denominator of 1/2 by 2, we get 2/4.

The expression now becomes:

2/4 + 3/4.

Adding the fractions:

(2 + 3) / 4 = 5/4.

Therefore, the numerical expression 1/2 - (-3/4) is equal to 5/4.
