A car engine is half filled and holds 15 litres of petrol.what fraction of the engine is full if it contains 18 litres of petrol?
a, 1/4
b, 2/3
c, 2/5
d, 3/5

• half of the car engine filed with 15 ltrs means full engine filed with 30 ltrs so the fraction will be=18/30=6/10=3/5

• Since half (1/2) filled car engine holds 15 ltrs of petrol
  
  we can write it as
  
  15 liters is contained in 1/2 as fraction
  
  so 1 liter will be contained in 1/30 as fraction
  
  hence 18 liters will be contained in 18/30 . i.e 3/5 as a fraction .
