**(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 1:-**

(a) 0.007 + 8.5 + 30.08

= 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)

= 343.89

**Question 2 :- Rashid-spent ₹35.75 for Maths-book and ₹32.60 for Science-book. Find the total-amount spent by Rashid.**

**Solution 2:-**

The money spent by Rashid for Maths book = ₹35.75

The money spent by Rashid for Science book = ₹32.60

So, the total money spent by Rashid on both books = ₹35.75 + ₹32.60 = ₹68.35

**Question 3 :- Radhika’s-mother gave her ₹10.50 and her-father gave her ₹15.80, find the total-amount given to Radhika by the parents.**

**Solution 3:-**

Money given by Radhika’s mother = ₹10.50

Money given by her father = ₹15.80

So, the total money given to her by her parents = ₹10.50 + ₹15.80 = ₹26.30

**Question 4 :- Nasreen bought 3m 20cm cloth for her-shirt and 2m 5cm cloth for her-trouser. Find the total length of cloth bought by her ?**

**Solution 4:-**

The length of cloth bought by Nasreen for her shirt = 3 m 20 cm = 3.20 m

The length of cloth brought by her for her trouser = 2 m 5 cm = 2.05 m

So, the total length of cloth bought by her = 3.20 m + 2.05 m = 5.25 m

**Question 5 :- Naresh walked 2km 35m in the morning and 1km 7m in the evening. How much distance did he walk in all?**

**Solution 5:-**

Distance walked by Naresh in the morning = 2 km 35 m = (2 + 351000) km = 2.035 km.

Distance walked by him in the evening = 1 km 7 m = (1 + 0.007) km = 1.007 km

So, the total distance walked by him in all = (2.035 + 1.007) km = 3.042 km

**Question 6 :- Sunita travelled 15km 268m by bus, 7km 7m by car and 500m on foot in order to reach her school. How far is her school from her residence?**

**Solution 6:-**

Distance travelled by Sunita by bus = 15 km 268 m = [15 + (268/1000)] = 15.268 km

Distance travelled by her by car = 7 km 7 m = [ 7 + (7/1000)] km = 7.007km

Distance travelled by her foot = 500 m = (500/1000) km = 0.500 km.

Total distance from her residence to school = (15.268 + 7.007 + 0.500) km = 22.775 km.

** Question 7 :- Ravi purchased 5kg 400g rice, 2kg 20g sugar and 10kg 850g flour. Find the total
weight of his purchases. **

**Solution 7 :- **

The weight of rice = 5kg 400g = 5.400 kg

The weight of sugar = 2kg 20g = 2.020 kg

The weight of flour = 10kg 850g = 10.850 kg

Total weight = (5.400 + 2.020 + 10.850) kg = 18.270 kg.
