1hour 15min : 30min

1hour=60min

(60min+15min) : 30min

75min : 30min

75/30 = 5 : 2 ans.........

b)2kg 250g : 5kg

(2kg×1000g) + 250g

2250 : 5kg

2250/5 = 450:1 ans..........

c)2m 30cm : 10cm

1m=100cm

(2m×100cm)+30cm

200cm+30cm : 10cm

230cm : 10 cm

230/10 = 23:1 ans.........

d)75paise : 2rupees 25paise

1rupee = 100paise
