Step 1: Arrange the numbers in ascending order based on their magnitudes. The magnitude of a number is its absolute value, which is the number without its sign. So, we ignore the negative signs for now and just focus on the numbers themselves: 5, 7, 2, 1.

Step 2: When we arrange these in ascending order, we get: 1, 2, 5, 7.

Step 3: Now, we put the signs back in. So, the numbers in ascending order are: 1, -2, -5, 7.

Step 4: To find the difference between the largest and smallest number, we subtract the smallest number from the largest: 7 - 1 = 6.

Step 5: To express this difference as a decimal fraction correct to one decimal place, we simply write it as 6.0.
