Question

4. Find the compound ratio of the ratios 250 mL : 1.450 L and 7 h 15 minutes: 12 h.​

Answer 1

Answer:

First part

1litre = 1000 ml

so 1.450 litres = 1450 ml

now, 250 ml : 1.450 litre

250 : 1450

25 : 145

5 : 29

second part

1 hour = 60 minutes

so, 7h 15 min = 7 × 60 + 15 = 435

12 hours = 12 × 60 = 720

now, 7h 15 min : 12 h

435 : 720

87 : 124
