Two numbers such that the greater number is 75 percent more than the lesser number
victus00 [196]
<h2>Greetings!</h2>

If x = the first number (equal to 1x) then the second number is 75% more than this.

This means the value of the bigger number is 100 + 75 (because 100 is the starting number and 75 is the percent bigger)

This can be shown with the following equation:

Amount * \frac{percentage}{100}

x *  \frac{175}{100} = 1.75x

1.75x is the value of the bigger number.


<h2>Hope this helps!</h2>
