NCERT In-text Question Page No. 245<\/span>
\nQuestion 1.
\nIn a class, there are 20 boys and 40 girls. What is the ratio of the number of boys to the number of girls?
\nAnswer:
\nNumber of boys = 20
\nNumber of girls = 40
\nRatio of boys to girls = \\(\\frac{20}{40}=\\frac{1}{2}=\\frac{1}{2}\\)
\nhence the required ratio is \\(\\frac{1}{2}\\)<\/p>\n

Question 2.
\nRavi walks 6 km in an hour while Roshan walks 4 km in an hour. What is the ratio of the distance covered by Ravi to the distance covered by Roshan?
\nAnswer:
\nDistance covered by Ravi in 1 hr = 6 km
\nDistance covered by Roshan in 1 hr = 4 km
\n\u2234 Ratio of distance covered Ravi in 1 hr to distance covered by Roshan in 1 hr = 6 km : 4
\n= \\(\\frac{6}{3}=\\frac{4}{2}\\)
\nNote:
\n(i) We donate ratio by the symbol
\n(ii) Ratio has no unit.
\n(iii) Two quantities can be compared only if they are in the same unit.
\n(iv) In a ratio the order of terms is very important. 2 : 3 and 3 : 2 are different ratios.<\/p>\n

\nQuestion 1.
\nSaurabh takes 15 minutes to reach school from his house and Sachin takes one hour to reach school from his house. Find the ratio of the time taken by Saurabh to the time taken by Sachin.
\nAnswer:
\nTime taken by Saurab = 15 minutes
\nTime taken by Sachin = 1 hour = 60 minutes
\n\u2234 Ratio of time taken by Saurabh to the time taken by Sachin
\n= \\(\\frac{\\text { Time taken by Saurabh }}{\\text { Time taken by Sachin }}\\)
\n= \\(\\frac{15}{10}=\\frac{15 \\div 15}{60 \\div 15}=\\frac{1}{4}\\) 1 : 4
\n[\u2235 HCF of 15 and 60 is 15]<\/p>\n

Question 2.
\nCost of a toffee is 50 paise and cost of a chocolate is \u20b9 10. Find the ratio of the cost of a toffee to the cost of a chocolate.
\nAnswer:
\nCost of Toffee = 50 paise
\nCost of chocolate = \u20b9 10 rupees
\n[\u2235 \u20b9 1 = 100 paise]
\n\u2234 10 \u20b9 = 1000 paise
\nSo, the cost of chocolate = 1000 paise
\nThe ratio of the cost of toffee to the cost of chocolate = \\(\\frac{50}{1000}\\) = 1 : 20<\/p>\n

\nQuestion 1.
\nDetermine if the following are in proportion.
\nIf yes, then write them in the proper form.
\n1. 1 : 5 and 3 : 15
\n2. 2 : 9 and 18 : 81
\n3. 15 : 45 and 5 : 25
\n4. 4 : 12 and 9 : 27
\n5. \u20b9 10 to \u20b915 and 4 to 6
\nAnswer:
\n1. 1 : 5 and 3 : 15
\nWe have, 3 : 15 = \\(\\frac{3}{15}=\\frac{3 \\div 3}{15 \\div 3}=\\frac{1}{5}\\) = 1 : 5
\n[ \u2235 HFC of 3 and 15 is 3]
\ni.e,. 1 : 5 and 3 : 15 are in proportion.
\nThus, the proper form is 1 : 5 :: 3 : 15<\/p>\n

2. 2 : 9 and 18 : 81
\nWe have, 18 : 81= \\(\\frac{18}{81}=\\frac{18 \\div 9}{81 \\div 9}=\\frac{2}{9}\\) = 2 : 9
\n[\u2235 HFC of 18 and 81 is 9]
\ni. e,. 2 : 9 and 18:81 are in proportion.
\nThus, the proper form is 2 : 9 :: 18:81<\/p>\n

3. 15 : 45 and 5 : 25
\nWe have, 15 : 45 = \\(\\frac{15}{45}=\\frac{15 \\div 15}{45 \\div 15}=\\frac{1}{3}\\) = 1 : 3
\n[ \u2235 HFC of 15 and 45 is 15]
\nWe have, 5 : 25 = \\(\\frac{5}{25}=\\frac{5 \\div 5}{25 \\div 5}=\\frac{1}{5}\\) = 1 : 5
\n[\u2235HCF of 5 and 25 is 5]
\n\u2235 1 : 3 \u2260 1 : 5 \u2234 15 : 45 \u2260 5 : 25
\ni. e,. 15 : 45 and 5 : 25 are not in proportion.<\/p>\n

4. 4 : 12 and 9: 27
\nWe have, 4 : 12 = \\(\\frac{4}{12}=\\frac{4 \\div 4}{12 \\div 4}=\\frac{1}{3}\\) = 1 : 3
\n[\u2235 HFC of 4 and 12 is 4]
\nAgain we have, 9 : 27 = \\(\\frac{9}{27}=\\frac{9 \\div 9}{27 \\div 9}=\\frac{1}{3}\\) =1:3
\n[\u2235 HFC of 9 and 27 is 9]
\n4 : 12 = 9 : 27
\nor 4 : 12 and 9 : 27 are in proportion,
\ni.e., 4 : 12 : : 9 : 27 is the correct form.<\/p>\n

5. \u20b9 10 to \u20b9 15 and 4 to 6
\nWe have, \u20b910 : \u20b915 = \\(=\\frac{10}{15}=\\frac{10 \\div 5}{15 \\div 5}=\\frac{2}{3}\\) = 2 : 3
\n[\u2235 HCF of 10 and 15 is 5]
\nAgain we have, 4 : 6 = \\(\\frac{4}{6}=\\frac{4 \\div 2}{6 \\div 2}=\\frac{2}{3}\\) = 1 : 3
\n[\u2235 HFC of 4 and 6 is 2]
\nThus \u20b9 10 : \u20b9 15 = 4 : 6.
\nor \u20b9 10, \u20b9 15, 4 and 6 are in proportion.
\nso, the correct from is \u20b9 10 : \u20b9 15 : : 4 : 6<\/p>\n

\nAnswer:
\n\u2235 Distance travelled by Kriti in 2 hours = 6 km
\n\u2234 Distance travelled by Kriti in 1 hour = \\(\\frac { 6 }{ 2 }\\) = 3 km
\n\u2234 Distance travelled by Karan in 1 hour = 5 km
\n\u2234 Distance travelled by Karan in 4 hours = 4 x 4 km = 16 km
\n\u2234 Distance travelled by Kriti in 1 hour = 3 km
\n\u2234 Distance travelled by Kriti in 4 hour = 3 x 4 km = 12 km
\nThus, the table is written as given below :
