Q1) Solve for N in the following n/3=6/9

Q2) Express 37.5% as a common fraction

Q3) Solve for x : 50 is 20% of x

Q4) 7 2/5% of x is equal to 74. solve for x.

• 3)
  Solve for x :
  50 is 20% of x
  50 = x*20/100
  x=250

• 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
  (37/5%) x = 74
  (37/(5 x100)) x = 74
  x = (74x100x5)37
  x = 1000

• 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
