Gujarat Board Textbook Solutions Class 6 Maths Chapter 8 Decimals Ex 8.5
Question 1.
Find the sum in each of the following:
(a) 0.007 + 8.5 + 30.08
(b) 15 + 0.632 + 13.8
(c) 27.076 + 0.55 + 0.004
(d) 25.65 + 9.005 + 3.7
(e) 0.75 + 10.425 + 2
(f) 280.69 + 25.2 + 38
Solution:
(a) 0.007 + 8.5 + 30.08
Thus, 0.007 + 8.5 + 30.08 = 38.587
(b) 15 + 0.632 + 13.8
Thus, 15 + 0.632 + 13.8 = 29.432
(c) 27.076 + 0.55 + 0.004
Thus, 27.076 + 0.55 + 0.004 = 27.63
(d) 25.65 + 9.005 + 3.7
Thus, 25.65 + 9.005 + 3.7 = 38.355
(e) 0.75 + 10.425 + 2
Thus, 0.75 + 10.425 + 2 = 13.175
(f) 280.69 + 25.2 + 38
Thus, 280.69 + 25.2 + 38 = 343.89

Question 4.
Nasreen bought 3 m 20 cm cloth for her shirt and 2 m 5 cm cloth for her trouser. Find the total length of cloth bought by her.
Solution:
Length of cloth bought:
for her shirt = 3 m 20 cm
for her trouser = 2 m 5 cm
ā“ Total length of cloth bought = (3 m 20 cm) + (2 m 5 cm)
= (3 + 0.20) m + (2 + 0.05) m = 3.20 m + 2.05 m = 5.25 m
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, in the evening = 1 km 7 m
ā“ Total distance walked by Naresh
= (2 km 35 m) + (1 km 7 m)
= (2 km + 35 m) + (1 km + 7 m)
= (2 + 0.035) km + (1 + 0.007) km = 3.042 km
Question 6.
Sunita traveled 15 km 268 m by bus, 7 km 7 m by car, and 500 m on foot in order to reach her school. How far is her school from her residence?
Solution:
Distance covered:
by bus = 15 km 268 m
by car = 7 km 7 m
on foot = 500 m
ā“ Total distance covered = (15 km 268 m) + (7 km 7m) + 500 m
= (15 + 0.268) km + (7 + 0.007) km + (0.500) km = 15.268 km + 7.007 km + 0.500 km 15.268
= 22.775 km
Thus, the required distance = 22.775 km.
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.
Solution:
Weight of rice = 5 kg 400 g
Weight of sugar = 2 kg 20 g
Weight of flour = 10 kg 850 g
ā“ Total weight = (5 kg 400 g) + (2 kg 20 g) + (10 kg 850 g)
= (5 + 0.400) kg + (2 + 0.020) kg + (10 + 0.850) kg
= 5.400 kg + 2.020 kg + 10.850 kg = 18.270 kg
Thus, the total weight of Raviās purchases = 18.270 kg.
