Question

A number + half of the number=15 what is the number?

Answer 1

Answer:

10

Step-by-step explanation:

let the number be n then half the number is $\frac{1}{2}$ n, then

n + $\frac{1}{2}$ n = 15

Multiply through by 2 to clear the fraction

2n + n = 30, that is

3n = 30 ( divide both sides by 3 )

n = 10

Thus the number is 10

Answer 2

Answer: the number is 10.

Step-by-step explanation:

Let the missing number be p

From the question, p + 1/2p = 15

1 1/2p = 15

1 1/2p can be written as 3/2p

3/2p= 15

Divide both sides by 3/2

p = 15 ÷ 3/2 = 15 x 2/3

P= 30/3 = 10

If p is 10;

1/2p = 10/2 =5.

The number is 10.

I hope this helps.
