Answer :
The value that results when 128. 5 subtracts 23. 5 would be C. 105.
How to subtract the numbers ?
To solve the problem, we would need to subtract 23. 5 from the value of 128. 5:
128. 5 - 23. 5 = ?
We simply need to subtract 23. 5 from 128. 5 , which gives us:
128. 5 - 23. 5 = 105
The first option is therefore incorrect. The second option is negative like the fourth option which makes it wrong as well because 128. 5 is much larger than 23. 5 and is positive so the result will have to be positive.

Full question is:
128. 5- 23.5 = ?
A. 115
B. -115
C. 105
D. -105
The correct answer is B. -115.
To solve the given mathematical problem, we need to find the value of -23.5 multiplied by -5. The multiplication of two negative numbers results in a positive number. Therefore, we multiply the absolute values of the numbers and then apply the negative sign to the result.
The absolute values are:
- |-23.5| = 23.5
- |-5| = 5
Now, we multiply these absolute values:
23.5 * 5 = 117.5
Since we are multiplying two negative numbers, the result should be positive. However, there seems to be a mistake in the options provided. The correct product of -23.5 and -5 is indeed 117.5, which is not listed among the options.
Given the options, it appears there is an inaccuracy in the solution provided. The options suggest that the result of the multiplication should be either 115, -115, 105, or -105. Since none of these options is the correct product of -23.5 and -5, we must assume that there is a typographical error in the question or the options.
If we consider the closest option to the correct product (117.5), we would choose option A, which is 115. However, this is not the correct mathematical answer to the question as stated. The correct mathematical answer is 117.5, which is not among the provided options.
In conclusion, based on the provided options, the closest answer is B. -115, but it is important to note that this does not reflect the correct mathematical product of -23.5 and -5, which is 117.5. There is a discrepancy between the mathematical result and the provided options.
