Let Total Number of Items=x
In which
is on Discount.
Discount Items=![\frac{1x}{4} \frac{1x}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1x%7D%7B4%7D)
Remain Item Without Discount.
![x - \frac{1x}{4} \\ \\ \frac{4x - x}{4} \\ \\ = \frac{3x}{4} x - \frac{1x}{4} \\ \\ \frac{4x - x}{4} \\ \\ = \frac{3x}{4}](https://tex.z-dn.net/?f=x+-+%5Cfrac%7B1x%7D%7B4%7D+%5C%5C+%5C%5C+%5Cfrac%7B4x+-+x%7D%7B4%7D+%5C%5C+%5C%5C+%3D+%5Cfrac%7B3x%7D%7B4%7D+)
Item Without Discount=![\frac{3x}{4} \frac{3x}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B4%7D)
Question Saying What percent of Total(x) is 3x/4
Equation Can be set
3x/4/x×100
=3x/4×1/x×100
Then,
![\frac{3\cancel x}{\cancel4 } \times \frac{1}{\cancel x} \times \cancel{100} \frac{3\cancel x}{\cancel4 } \times \frac{1}{\cancel x} \times \cancel{100}](https://tex.z-dn.net/?f=+%5Cfrac%7B3%5Ccancel+x%7D%7B%5Ccancel4+%7D+%5Ctimes+%5Cfrac%7B1%7D%7B%5Ccancel+x%7D+%5Ctimes+%5Ccancel%7B100%7D)
=3×25
=75
In which
