A percentage is simply a fraction with denominator 100. For example, you have that 74% is the same as 74/100.
So, you have to turn 2/50 into a fraction with denominator 100. If you multiply both numerator and denominator by 2, you get
[tex] \dfrac{2}{50} = \dfrac{4}{100} = 4\%[/tex]
To find what percentage of bikes are defective we first have to find the ratio. The ratio can be found by dividing both sides of the division. If we divide 2 by 2 we get 1 and if we divide 50 by 2 we get 25.
After we found our ratio which is 1 to 25 we can set up an equation that will help us solve the problem. Such as
[tex] \frac{1}{25} = \frac{x}{100} [/tex]
We cross multiply do
[tex]1 \times 100 = x \times 25 [/tex]
Complete the multiplication
[tex]100 = 25x[/tex]
Simplify
[tex]4 = x[/tex]
