GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 4
Here,
2 tens – 1 ten = 1 ten
1 ten = 10 ones
Thus, ₹ 20.75 – ₹ 18.25 = ₹ 2.50

(b) 250 m – 202.54 m
Here, 250 m = 250.00 m
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 5
Thus, 250 m – 202.54 m = 47.46 m

(c) ₹ 8.40 – ₹ 5.36
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 1
∴ ₹ 8.40 – ₹ 5.36 = ₹ 3.04

(d) 5.206 km – 2.051 km
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 2
Thus, 5.206 km – 2.051 km = 3.155 km

(e) 2.107 kg – 0.314 kg
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 3
Thus, 2.107 kg – 0.314 kg = 1.793 kg

Question 2.
Find the value of:
(a) 9.756 – 6.28
(b) 21.05 – 15.27
(c) 18.5 – 6.79
(d) 11.6 – 9.847
Solution:
(a) 9.756 – 6.28
Since, 6.28 = 6.280
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 6
Thus, 9.756 – 6.28 = 3.476

(b) 21.05 – 15.27
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 7
∴ 21.05 – 15.27 = 5.78

(c) 18.5 – 6.79
We have 18.5 = 18.50
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 8
∴ 18.5 – 6.79 = 11.71

(d) 11.6 – 9.847
We have 11.6 = 11.600
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 9
Thus, 11.6 – 9.847 = 1.753

Question 5.
Tina had 20 m 5 cm long cloth. She cuts 4 m 50 cm length of cloth from this for making a curtain. How much cloth is left with her?
Solution:
The total length of cloth with Tina = 20 m 5 cm
Length of the cloth used for curtain = 4 m 50 cm
Length of cloth left with her = 20 m 5 cm – 4 m 50 cm
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 12
= (20 + 0.05) m – (4 + 0.50) m
= 20.05 m – 4.50 m
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 13
∴ 20.05 m – 4.50 m = 15.55 m
Thus, the length of cloth left = 15.55 m

Question 6.
Namita travels 20 km 50 m every day. Out of this, she travels 10 km 200 m by bus and the rest by auto. How much distance does she travel by auto?
Solution:
Total distance to be travelled = 20 km 50 m
Distance travelled by bus = 10 km 200 m
The remaining distance to be travelled by auto
= 20 km 50 m – 10 km 200 m
= (20 km + 50 m) – (10 km + 200 m)
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 14
= (20 +50 m) – (10 km + 200 m)
= 20.050 km – 10.200 km
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 15
Thus, the distance travelled by auto = 9.850 km

Question 7.
Aakash bought vegetable weighing 10 kg. Out of this, 3 kg 500 g is onions, 2 kg 75 g is tomatoes and the rest is potatoes. What is the weight of the potatoes?
Solution:
Total weight of vegetables = 10 kg
Weight of onions = 3 kg 500 g
Weight of tomatoes = 2 kg 75 g
Total weight of onions + tomatoes = 3 kg 500 g + 2 kg 75 g
GSEB Solutions Class 6 Maths Chapter 8 Decimals ex 8.6 img 16
Now, weight of potatoes
= 10 kg 0 g – 5.575 kg
= (10,000 – 5.575) kg = 4.425
∴ Weight of potatoes = 4.425 kg
