**Ex 8.5 Class 6 Maths Question 7.**

**Ravi purchased 5 kg 400 g rice, 2 kg 20 g sugar and 10 kg 850 g flour. Find the total weight of his purchases.**

**Solutions:**

= [(2 + 20/1000)] kg

= 2.020 kg

Weight of flour = 10 kg 850 g

= [(10 + 850/1000)] kg

= 10.850 kg

Total weight of his purchases is

5.400

2.020

+ 10.850

___________
