## PSEB Solutions for Class 7 Maths Chapter 2 Fractions and Decimals Ex 2.5

1. Which is greater decimal number ?

Question (i).
0.9 or 0.4
0.9 or 0.4
Here in 0.9 tenth place is greater than tenth place of 0.4.
9 > 4
∴ 0.9 > 0.4

Question (ii).
1.35 or 1.37
1.35 or 1.37
Whole number parts of both number are equal
So, we have to compare decimal part
Also digits at tenths place are also equal.
Hundredths part of 1.37 is greater than hundredth the part of 1.35
∴ 1.37 > 1.35

Question (iii).
10.10 or 10.01
10.10 or 10.01
Whole number parts of both numbers are equal
So, we have to compare decimal part
Tenths part of 10.10 is greater than tenths part of 10.01
∴ 10.10 > 10.01

Question (iv).
1735.101 or 1734.101
1735.101 or 1734.101
Whole number part of 1735.101 is greater than whole number part of 1734.101
∴ 735.101 > 1734.101

Question (v).
0.8 or 0.88.
0.8 or 0.88
Here tenths place in both the number is same and hundredths place in 0.88 is greater than the hundredths place in 0.8.
∴ 0.88 > 0.8

2. Write following decimal number in the expanded form :

Question (i).
40.38
40.38 = 40 + 0 + .3+ .08
= 4 × 10 + 0 + 3 × $$\frac {1}{10}$$ + 8 × $$\frac {1}{100}$$

Question (ii).
4.038
4.038 = 4 + 0.0 + 0.03 + 0.008
4 + 0 × $$\frac {1}{10}$$ + 3 × $$\frac {1}{100}$$ + 8 × $$\frac {1}{1000}$$

Question (iii).
0.1038
0.4038 = 0 + 0.4 + 0.00 + 0.003 + 0.0008
= 0 + 4 × $$\frac {1}{10}$$ + 0 × $$\frac {1}{100}$$ + 3 × $$\frac {1}{1000}$$ + 8 × $$\frac {1}{10000}$$

Question (iv).
4.38.
4.38 = 4 + 0.3 + 0.08
= 4 + 3 × $$\frac {1}{10}$$ + 8 × $$\frac {1}{100}$$

3. Write the place value of 5 in the following decimal numbers :

Question (i).
17.56
Place value of 5 in 17.56 = 0.5
= $$\frac {5}{10}$$

Question (ii).
1.253
Place value of 5 in 1.253 = 0.05
= $$\frac {5}{100}$$

Question (iii).
10.25
Place value of 5 in 10.25 = 0.05
= $$\frac {5}{100}$$

Question (iv).
5.62.
Place value of 5 in 5.62 = 5

4. Express in rupees using decimals :

Question (i).
55 paise
55 paise = ₹ $$\frac {55}{100}$$
= ₹ 0.55

Question (ii).
55 rupees 5 paise
55 rupees 5 paise = 55 rupees + 5 paise
= ₹ 55 + ₹ $$\frac {5}{100}$$
= ₹ 55 + ₹ 0.5
= ₹ 55.05

Question (iii).
347 paise
347 paise = ₹ $$\frac {347}{100}$$
= ₹ 3.47

Question (iv).
2 paise.
2 paise = ₹ $$\frac {2}{100}$$
= ₹ 0.02.

5. Express in km :

Question (i).
350 m
350 m = $$\frac {350}{1000}$$ km
= 0.350 km
[Since 1000 m = 1 km,
∴ 1 m =$$\frac {1}{1000}$$ km]

Question (ii).
4035 m
4035 m = $$\frac {4035}{1000}$$ km
= 4.035 km

Question (iii).
2 km 5 m
2 km 5 m = 2 km + 5 m
= 2 km + $$\frac {5}{1000}$$ km
= 2.05 km
