Let the number be x.
'Subract ¼ from the number' is mathematically written as 'x - ¼'.
Multiplying the above obtained result by ½ is mathematically shown as:
'(x - ¼) × ½'.
According to the question,
(x−14)×12=14
⇒ x−14=2×14
(by multiplying both the sides by 2)
⇒ x−14=12
⇒ x = 12+14
(by transposing ¼ from LHS to the RHS)
⇒ x = 34
So, the required number is 34.
