Final answer:
The subtraction of 79/40 from 162.5%, after converting the percentage to a decimal (1.625), results in either 0.35 or -0.35, depending on the order of subtraction. However, neither result matches the options provided in the multiple-choice answers, suggesting there might be an error in the question or the options.
Step-by-step explanation:
To subtract 79/40 from 162.5%, first, we need to convert the percentage to a fraction or decimal so that we can perform the subtraction. The percentage 162.5% can be written as 1.625 when converted to a decimal. Thus, our computation becomes:
- Step 1: Convert the percentage to a decimal: 162.5% = 1.625
- Step 2: Perform the subtraction: 79/40 - 1.625
First, express 79/40 as a decimal which is 1.975. Then, subtract 1.625 from 1.975:
1.975 - 1.625 = 0.35
This calculation gives us the result 0.35, which is not provided in the multiple-choice answers. If we consider that the subtraction should be done the other way around, that is 1.625 - 79/40:
1.625 - 1.975 = -0.35
However, this also does not correspond to any of the options given. It seems that there is a mistake in the question or the choices provided. Without the correct options, we cannot determine the intended answer from the provided list (a) through (d).
