20%=20/100
20% of 30=20*30/100=600/100=6
30%=30/100
30% of 20=30*20/100=600/100=6
m% of n=m*n/100
n% of m=n*m/100
m% of n is always equal to n% of m?
Examples:
40% of 60=40*60/100=2400/100=24
60% of 40=60*40/100=2400/100=24
70% of 90=70*90/100=6300/100=63
90% of 70=90*70/100=6300/100=63
20% of 30=20*30/100=600/100=6
30%=30/100
30% of 20=30*20/100=600/100=6
m% of n=m*n/100
n% of m=n*m/100
m% of n is always equal to n% of m?
Examples:
40% of 60=40*60/100=2400/100=24
60% of 40=60*40/100=2400/100=24
70% of 90=70*90/100=6300/100=63
90% of 70=90*70/100=6300/100=63
m% of n is always equal to n% of m
