A mixed fraction is a fraction that contains a whole number and a fraction whose denominator is greater than the numerator. A mixed fraction can be converted as,
2 1/2
= (2×2 + 1)/2
= 5/2
= 2.5
The sum of 1.25 and (−1 3/4) can be done as,
1.25 + (−1 3/4)
= 1.25 - 1.75
= -0.5
The opposite of 2 1/2 is -2 1/2, therefore, the addition of the opposite of 2 1/2 to the sum of 1.25 and (−1 3/4) is,
-0.5 + (-2 1/2)
= -0.5 - 2.5
= -3
Hence, the addition of the opposite of 2 1/2 to the sum of 1.25 and (−1 3/4) is -3.
