(ii) Comparing the digits at tenths places, we have \n7 > 5 \n\u2234 0.7 > 0.5 \nSo, 0.7 is greater.<\/p>\n
(iii) Comparing the digits at ones place, we have \n7 > 0 \n\u2234 7 > 0.7 \nSo, 7 is greater.<\/p>\n
(iv) Since the digits at ones place are same, comparing the digits at tenths place, we have \n3 < 4 \n\u2234 1.37 <1.49 \nSo, 1.49 is greater.<\/p>\n
(v) Since the digits at ones place are same, comparing the digits at tenths place, we have \n0 < 3 \n\u2234 2. 03 < 2.30 \nSo, 2.30 is greater.<\/p>\n
(vi) 0.8 can be written as 0.80. Now, digits at tenths place are same, comparing the digits at hundredths place, we have \n0 < 8 \n\u2234 0.80 <0.88 \nSo, 0.88 is greater.<\/p>\n

Question 2. \nExpress as rupees using decimals: \n(i) 7 paise \n(ii) 7 rupees 7 paise \n(iii) 77 rupees 77 paise \n(iv) 50 paise \n(v) 235 paise. \nAnswer: \n(i) 7 paise = \u20b9 = 7 \u00d7 \\(\\frac{1}{100}=\\frac{7}{100}\\) = \u20b9 0.07<\/p>\n
(ii) rupees 7 paise = \u20b9 = 7 + 7 \u00d7 \\(\\frac{1}{100}\\) \n= \u20b9 7 + \u20b9 0.07 = \u20b9 7.07<\/p>\n
(iii) 77 rupees 77 paise = \u20b9 77 + \u20b9 77 \u00d7 \\(\\frac{1}{100}\\) = \u20b9 77 + \u20b9 0.77 = \u20b9 77.77<\/p>\n
(iv) 50 paise = \u20b9 50 \u00d7 \\(\\frac{1}{100}\\) = \u20b9 0.50<\/p>\n
(v) 235 paise= 200 paise + 35 paise \n= \u20b9 2 + \u20b9 35 \u00d7 \\(\\frac{1}{100}\\) = \u20b9 2 + \u20b9 0.35 \n= \u20b9 2.35<\/p>\n
Question 3. \n(i) Express 5 cm in metre and kilometre \n(ii) Express 35 mm in cm, m, and km \nAnswer: \nWe know that 100 cm = 1 m, \n1000 m = 1 km \n(i) 5cm = \\(\\frac{5}{100}\\) m = 0.05 m \n5 cm = \\(\\frac{5}{100 \\times 100}\\) km \n= 0.00005 km.<\/p>\n
(ii) We know that 1 cm =10 mm \n35 mm = \\(\\frac{35}{10 \\times 100}\\) m = \\(\\frac{35}{1000}\\) \n35mm = \\(\\frac{35}{10 \\times 100}\\) m = \\(\\frac{35}{1000}\\) \n= 0.035 m \n35 mm \\(\\frac{35}{10 \\times 100 \\times 1000}\\) km \n= \\(\\frac{35}{1000000}\\) = 0.000035 km<\/p>\n
<\/p>\n
Question 4. \nExpress in kg: \n(i) 200 g \n(ii) 3470 g \n(iii) 4 kg 8 g \nAnswer: \nWe know that 1000 g = 1 kg \n(i) 200 g = \\(\\frac{200}{1000}\\) kg = \\(\\frac{2}{10}\\) kg = 0.2 kg \n(ii) 3470 g = \\(\\frac{3470}{1000}\\) kg = \\(\\frac{347}{100}\\) kg = 3.47 kg \n(iii) 4 kg 8 g = 4 kg + \\(\\frac{8}{1000}\\) kg \n= 4 kg + 0.008 kg = 4.008 kg<\/p>\n
Question 5. \nWrite the following decimal numbers in the expanded form: \n(i) 20.03 \n(ii) 2.03 \n(iii) 200.03 \n(iv) 2.034 \nAnswer: \n <\/p>\n

(ii) In 21.37, the digit 2 is at the tens place \n\u2234 place value of 2 is 2 \u00d7 10 = 20.<\/p>\n
(iii) In 10.25, the digit 2 is at the tenths place \n\u2234 place value of 2 is 2 \u00d7 \\(\\frac{1}{10}=\\frac{2}{10}\\)<\/p>\n
(iv) In 9.42, the digit 2 is at the hundredths place \n\u2234 The place value of 2 is 2 \u00d7 \\(\\frac{1}{100}=\\frac{2}{100}\\)<\/p>\n
(v) In 63.352, the digit 2 is at the thousandths place \n\u2234 The place value of 2 is 2 \u00d7 \\(\\frac{1}{1000}=\\frac{2}{100}\\)<\/p>\n
Question 7. \nDinesh went from place A to place B and from there to place C. A is 7.5 km from B and B is 12.7 km from C. Ayub went from place A to place D and from there to place C. D is 9.3 km from A and C is 11.8 km from D. Who travelled more and by how much? \nAnswer: \nDistance from A to B = 7.5 km \nDistance from B to C = 12.7 km \nDistance from A to C through \nB = (7.5 + 12.7) km \n= 20.2 km \n\u2234 Distance travelled by Dinesh = 20.2 km \n \nAgain \nDistance from A to D = 9.3 km \nDistance from D to C = 11.8 km \nDistance from A to C through D \n= (9.3 + 11.8) km \n= 21.1 km \n\u2234 Distance travelled by Ayub = 21.1 km 21. 1 > 20.2 \n\u2234 Ayub travelled more distance. \nDifference = 21.1 km – 20.2 km \n= 0.90 km (or) 900 m \n\u2234 Ayub travelled more distance by 900 m<\/p>\n

Question 8. \nShyama bought 5 kg 300 g apples and 3 kg 250 g mangoes. Sarala bought 4 kg 800 g oranges and 4 kg 150 g bananas. Who bought more fruits? \nAnswer: \nSince, Shyama bought 5 kg 300 g apples and 3 kg 250 g mangoes \nTotal fruits bought by Shyama = 5 kg \n300 g + 3 kg 250 g = 8 kg 550 g \nSince, Sarala bought 4 kg 800 g oranges and 4 kg 150 g bananas \nTotal fruits bought by Sarala \n= 4 kg 800 g + 4 kg 150 g = 8 kg 950 g \n8.950 > 8.550 \nSo, Sarala bought more fruits \nDifference in weight = 8 kg 950 g – 8 kg 550 g = 0 kg 400 g \n= 400 g or \\(\\frac{400}{1000}\\)kg = 0.4 kg<\/p>\n
