Answer:
The number is 50.
Step-by-step explanation:
If we express the percentage x% in the form of ratio then it can be written as 
.
Now, it is asked which number if we make 44 % will give 22.
Let the number is given by x.
Then expressing the % as ratio we can write 
⇒ 
( Answer )
a.
Let
5x = number of games won
2x = number of games lost
The total number of win and lose is 154. So
5x + 2x = 154
Solving for x,
7x = 154
x = 22
Therefore, the number of games won is 5*22=110 and the number of games lost is 2*22 is 44.
b.
Let
6x = first side of the triangle
7x = second side of the triangle
9x = third side of the triangle
The perimeter of a triangle is the total of all sides. So,
6x + 7x + 9x = 88
22x = 88
x = 4
Therefore, the three lengths of the side are 6*4=24, 7*4=28, and 9*4 = 36
