  2. 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
