About

Percent X

Features
Read full description

This is a simple app that handles daily percentage tasks in a neat new way.The page with the three blue fields allows you to select the three numbers you know. You must put the VALUES and PERCENTAGES either horizontally or vertically, NOT diagonally. The real calculation is X = (C / A) * B A B C X If your X is a VALUE, put the other VALUE in either B or C, then the corresponding PERCENTAGES Ex: What is 30% of 200? A=100 B=200 C=30 or A=100 B=30 C=200 If your X is a PERCENTAGE, put the other PERCENTAGE in either B or C, then the corresponding VALUES Ex: What % of 200 is 30? A=200 B=100 C=30 or A=200 B=30 C=100 To see more apps like this, go to www.discobajas.com
