You have to divide 2500 by 1800
2500/1800=more or less 1,39
And now multiply by 100 to get percentages
 1,39*100=139
2500 is 139% of 1800

Though maybe you meant the other way around, in which case it's
1800/2500=0,72
0,72*100=72
1800 is 72% of 2500

X/100 * 1800 = 2500
x/100 = 2500/1800
x = 2500 /1800 *100
x = 138.888....%
