Answer:
10
Step-by-step explanation:
let the number be n then half the number is [tex]\frac{1}{2}[/tex] n, then
n + [tex]\frac{1}{2}[/tex] 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: 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.
