= 0.007 + 8.500 + 30.080 (making like decimals)
= 38.587

(b) 15 + 0.632 + 13.8
= 15.000 + 0.632 + 13.800 (making like decimals)
= 29.432

(c) 27.076 + 0.55 + 0.004
= 27.076 + 0.550 + 0.004 (making like decimals)
= 27.630

(d) 25.65 + 9.005 + 3.7
= 25.650 + 9.005 + 3.700 (making like decimals)
= 38.355

(e) 0.75 + 10.425 + 2
= 0.750 + 10.425 + 2.000 (making like decimals)
= 13.175

(f) 280.69 + 25.2 + 38
= 280.69 + 25.20 + 38.00 (making like decimals)

Length of cloth brought by her for her trouser = 2 m 5 cm = 2.05 m
Total length of cloth bought by her = 3.20 m + 2.05 m = 5.25 m

Ex 8.5 Class 6 Maths Question 5.
Naresh walked 2 km 35 m in the morning and 1 km 7 m in the evening. How much distance did he walk in all?

Solution:

Distance walked by Naresh in the morning = 2 km 35 m = (2 + 35/1000) km = 2.035 km.
Distance walked by him in the evening = 1 km 7 m = (1 + 7/1000) km = 1.007 km 1000)
∴ Total distance walked by him in all
= (2.035 + 1.007) km
= 3.042 km
