Question 964346
Start with 1.25.
Change to 1.25+0.75=2.00.


Amount of increase was given, 0.75.
What PERCENT increase, how many parts of 100 original parts?


{{{0.75/1.25=p/100 }}}, a proportion.
p is the number of parts in one-hundred parts of the starting number.
Seventy five hundreds is how many parts per hundred original parts of 1.25?


Just solve the proportion.


{{{(0.75/1.25)*100}}}

{{{(75/125)100}}}


{{{((75)/(5*25))100}}}


{{{((25*3)/(5*25))100}}}


{{{((cross(25)*3)/(5*cross(25)))*100}}}


{{{(3/5)*100}}}


{{{3(100/5)}}}


{{{3*20}}}
