q1) n/3=6/9
n=(6/9)3
n=2
q2) (37.5)/100=3/8
q3) x/50 = 20/100
x =(20/100)50
x = 10
q4) (7 2/5%)x = 74

1) n/3=6/9
=>n=6X3/9
=>n=2

2) 37.5=375/10
=75/2

3) x:50=20%of x
=>x/50=x*20/100
=>x/50=20x/100
=>100x=1000x
Now, x must be 0 so that both sides are equal

Thus, x=0

4) 72/5% of x=74
=>x X (72/5)/100 = 74
=>72x/500=74
=>x=74X500/72
=>x=513.89
