Answer: None of the expressions provided in the options are equivalent to the expression [tex]-24 \frac{1}{2} + 16.5 - 4[/tex]
Step-by-step explanation:
To convert from mixed numbers to decimal numbers, we must add the fraction to the whole number part.
Given the following expression:
[tex]-24 \frac{1}{2} + 16.5 - 4[/tex]
Its sum is:
[tex]-(24+\frac{1}{2}) + 16.5 - 4=-12[/tex]
An expressio equivalent to the expression above must gives us the same result.
First option:
[tex]24\frac{1}{2} - 16.15 - 4 =4.35[/tex] (It's not equivalent)
Second option:
[tex]16.15 - 28.5 =-12.35[/tex] (It's not equivalent)
Third option:
[tex]-28.5 + 16.15 =-12.35[/tex] (It's not equivalent)
Fourth option:
[tex]-20 \frac{1}{2}+ 16.5=-4[/tex] (It's not equivalent)
Fifth option:
[tex]12.15 -24 \frac{1}{2}=-12.35[/tex] (It's not equivalent)
