To calculate the subtraction as described, follow these steps:
Step 1: Find the sum of 13 1/2 and 60 1/2.
Sum = 13 1/2 + 60 1/2 = 74
Step 2: Find the sum of 15 1/2 and 6 3/4.
Sum = 15 1/2 + 6 3/4 = 22 1/4
Step 3: Subtract the sum from Step 1 from the sum in Step 2.
Difference = 22 1/4 - 74
Now, we need to perform the subtraction. To do this, let's express 74 as an improper fraction so that we can perform the subtraction with like terms:
74 = 74/1
Now, subtract the fractions:
Difference = 22 1/4 - 74/1
To subtract fractions, you need to have a common denominator. The common denominator for 4 and 1 is 4. So, let's convert 74/1 to have a denominator of 4:
74/1 = 74/1 * 4/4 = 296/4
Now, the subtraction becomes:
Difference = 22 1/4 - 296/4
To subtract the fractions, the whole numbers must be converted to fractions with a denominator of 4:
22 = 22/1 * 4/4 = 88/4
Now, the subtraction becomes:
Difference = 88/4 - 296/4
Now, you can subtract the fractions:
Difference = (88 - 296)/4
Difference = -208/4
Finally, simplify the fraction:
Difference = -52
So, the result of subtracting the sum of 13 1/2 and 60 1/2 from the sum of 15 1/2 and 6 3/4 is -52.
