I disagree with Shannon's statement. While it's true that 7 - 5 = 2, 5 - 1 = 4, and 8 - 3 = 5, these are individual digit subtractions. When subtracting multi-digit numbers like 758 and 513, we need to consider place value.
To subtract mixed numbers with unlike denominators, we first need to rewrite them so that they have a common denominator. Then, we subtract the fractions separately and perform the subtraction for the whole numbers.
Let's demonstrate the subtraction of 513 from 758:
758 - 513
Step 1: Rewrite the mixed numbers with a common denominator:
758 = 700 + 50 + 8
513 = 500 + 10 + 3
Step 2: Subtract the fractions:
50 - 10 = 40
8 - 3 = 5
Step 3: Subtract the whole numbers:
700 - 500 = 200
Step 4: Combine the results:
200 + 40 + 5 = 245
So, the correct result of 758 - 513 is indeed 245. However, Shannon's explanation is not accurate as it doesn't consider the place value of each digit when subtracting multi-digit numbers.
