Solution and Explanation

Approach Solution 1:

Explanation: the given condition states to find the number of times 2 - 0.5 is 1 -0.5. ;
Accordingly, let the number of times be x. ;
2-0.5 = x(1-0.5)
1.5 = 0.5x
=> x = 3
Hence, the answer is 3 implying that 1 - 0.5 is 3 times to the number 2 - 0.5.which states that option E is the right answer. ‘

Approach Solution 2:

Explanation: As asked the number of times 1 - 0.5 gives 2 - 0.5 it is important that the unknown number of times be x. ;
To find a solution, it is important to equate the given data t. This is as follows: ;
1.5 - x(0.5) ;
=> x = 1.5/0.5 ;
=> x = 15/5 ;
=> x - 3 ;
Hence, 1-0.5 needs to be 3 times that would help in getting the number 2 - 0.5. Therefore, the correct answer is C.
