d. 50.157
The correct answer and explanation is:
To solve 42.56 – 7577, let’s first make sure the numbers are properly aligned.
42.56 is a decimal number, and 7577 is a whole number. To make the subtraction easier, it’s best to write the second number with a decimal point. So, 42.56 – 7577 becomes 42.5600 – 7577.0000.
Now, start subtracting from the rightmost digits:
- In the thousandths place, you can’t subtract 7 from 0, so you borrow 1 from the hundredths place (making the hundredths place 4).
- Subtracting 7 from 10 gives 3, so the thousandths place becomes 3.
- Move to the hundredths place: After borrowing, it’s 4, so 4 – 0 is 4.
- In the tenths place, 5 – 0 is 5.
- Now, subtract the whole numbers: 42 – 7577, which gives -7534.
Thus, 42.56 – 7577 = -7534.44.
Since the answer options provided don’t include negative numbers, it seems the question may have a mistake or a misprint. If you meant to subtract 42.56 from 7577, the correct answer would be:
