Question

13. When one-fourth of a number is subtracted from half of itself the result is 15/2 . Find the number.​

Answer 1

Step-by-step explanation:

let the number be x

x/2-x/4=15/2

2x/4-x/4=15/2

x/4=15/2

x=15/2*4

x=15*2

30 is the right answer

Hope it helps ✌✌

Answer 2

Answer: x = 30

Step-by-step explanation:

Let the Number be x

∴ So, one- fourth of that number will be 1/4 * x = x/4

∴ Half of that number will be 1/2 * x = x/2

According to the question, The equation formed would be:

x/2 - x/4 = 15/2

Let us Solve for x

x/2 - x/4 = 15/2

x*2/2*2 - x/4 = 15/2 (Equalising the denominators)

2x/4 - x/4 = 15/2

x/4 = 15/2

x*2 = 15*4 (Cross Multiplication)

2x = 60

x = 60/2

∴ x = 30

So, The Number is 30.
