Exercise 8.4
Q1. दशमलव का प्रयोग कर रूपए में बदलिए :
(a) 5 पैसे
हल : 1 पैसा = 1/100
5 पैसे = 1/100 x 5 = 0.05
(b) 75 पैसे
हल : 1 पैसा = 1/100
75 पैसे = 1/100 x 5 = 0.75
(c) 20 पैसे
हल : 1 पैसा = 1/100
20 पैसा = 1/100 x 5 = 0.05
(d) 50 रूपए 90 पैसे
हल : 1 पैसा = 1/100
50 + 90 पैसा = 50 + 1/100 x 90 = 50.90
(e) 725 पैसे
हल : 1 पैसा = 1/100
725 पैसे = 1/100 x 725 - 725 /100 = 7.25
Q2. दशमलव का प्रयोग कर मीटर में व्यक्त करिए :
(a) 15 सेमी
हल : 1 cm = 1/100 m
15 cm = 1/100 x 15 = 0.15 m
(b) 6 सेमी
हल : 1 cm = 1/100 m
6 cm = 1/100 x 6 = 0.06 m
(c) 2 मी 45 सेमी
हल : 1 cm = 1/100 m
2 m 45 cm = 2 + 1/100 x 45 = 2.45 m
(d) 9 मी 7 सेमी
हल : 1 cm = 1/100m
9 m 7cm = 9 + 1/100 x 7 = 9.07 m
(e) 419 सेमी
हल : 1 cm = 1/100 m
419 cm = 1/100 x 419 = 419/100 = 4.19m
Q3. दशमलव का प्रयोग कर सेमी में करिए :
(a) 5 मिमी
हल : 1 मिमी = 1/10 cm
5 मिमी = 1/10 x 5 = 0.5
(b) 60 मिमी
हल : 1 मिमी = 1/10 cm
60 मिमी = 1/10 x 60 = 6 cm
(c) 164 मिमी
हल : 1 मिमी = 1/10 cm
164 मिमी = 1/10 x 164 = 16.4 cm
(d) 9 सेमी 8 मिमी
हल : 1 मिमी = 1/10 cm
9 cm 8 मिमी = 9 + 1/10 x 8 = 9 + 0.8 = 9.8 cm
(e) 93 मिमी
हल : 1 मिमी = 1/10 cm
93 मिमी = 1/10 x 93 = 9.3 cm
Q4. दशमलव का प्रयोग कर किमी में लिखिए :
(a) 8 मी
हल : 1 मी = 1/1000 km
8 m = 1/1000 x 8 = 0.008 km
(b) 88 मी
हल : 1 मी = 1/1000 km
88 मी = 1/1000 x 88 = 0.088 km
(c) 8888 मी
हल : 1 मी = 1/1000 km
8888 मी = 1/1000 x 8888 = 8.888 km
(d) 70 किमी 5 मी
हल : 1 मी = 1/1000 km
70 km 5 मी = 70 + 1/1000 x 5 = 70.005 km
Q5. दशमलव का प्रयोग कर किग्रा में लिखिए :
(a) 2 ग्रा
हल : 1 ग्रा = 1/1000 kg
2g = 1/1000 x 2 = 0.0002 kg
(b) 100 ग्रा
हल : 1 ग्रा = 1/1000 kg
100 ग्रा = 1/1000 x 100 = 0.1 kg
(c) 3750 ग्रा
हल : 1 ग्रा = 1/1000 x 3750 = 3.750 kg
(d) 5 किग्रा 8 ग्रा
हल : 1 ग्रा = 1/1000 kg
5 kg 8 ग्रा = 5 + 1/1000 x 8 = 5.008 kg
(e) 26 किग्रा 50 ग्रा
हल : 1 ग्रा = 1/1000 kg
26 kg 50 ग्रा = 26 + 1/1000 x 50 = 26.050 kg
