Percent of constant changing total value

hello!

i have been working on code time, , seems working, ecxept part led's should turn on.

i have 3 sensors each has led.


what want having led turn on, when specific sensor 10% or over, total value.

for example

sensor1 = 10        sensor2= 3      sensor3= 30


now total value 43.

if sensor1 gets on 20 of total value, led1 should turn on.

sensor1 23%.

next reading shows

sensor1 = 10        sensor2= 3      sensor3= 40

now sensor1 19%. , led should turn off..

i have tried simple

sensor1/(sensor1+sensor2+senor3)*100 > 20,
digitalwrite (led1, high.)


but turning on when sensor1 above 20 reading. not 20%  doing wrong?

well, isn't code, should post actual code you're trying.
