name the additive inverse, opposite of each number.
1.8 - 8+(-8)= 0
2.5 - 5+(-5)= 0
3.3/4 - 3/4+(-3/4)=0
4. 1 1/2 - 1 1/2+(1 1/2)=0
To find the additive inverse or opposite of a number, you need to change its sign.
1. For the number 1.8, its additive inverse or opposite is -1.8. This means that 1.8 + (-1.8) equals 0.
2. Similarly, for the number 2.5, its additive inverse or opposite is -2.5. This means that 2.5 + (-2.5) equals 0.
3. For the fraction 3/4, its additive inverse or opposite is -3/4. This means that 3/4 + (-3/4) equals 0.
4. Lastly, for the mixed number 1 1/2, its additive inverse or opposite is -1 1/2. This means that 1 1/2 + (-1 1/2) equals 0.
To find the additive inverse of a number, simply change its sign from positive to negative or vice versa.
