Solution:

If 1/2 is subtracted from a number and the difference is multiplied by 4, the result is 5.

We have to find the number.

Let the number be x.

1/2 is subtracted from the number can be written as x - 1/2

The difference is multiplied by 4 can be represented as 4(x - 1/2)

According to the question,

4(x - 1/2) = 5

x - 1/2 = 5/4

x = 5/4 + 1/2

x = (5 + 2)/4

x = 7/4

Therefore, the number is 7/4.
