Ratio and Proportion Problems for Class 6 :

In this section, we are going to see the problems on ratio and proportion for class 6. ## Ratio and Proportion Problems for Class 6 - Practice Questions

Now, let us look at some practice questions and step by step solution on "Ratio and proportion problems for class 6"

Question 1 :

If there are two lengths such that a = 90 cm and b = 120 cm, then find the ratio between them.

Solution :

a : b  =  90 : 120

a : b  =  3 : 4

Hence, the ratio between the two lengths is

3 to 4

From question no. 2 to question no.8, please use the information in the table given below. Question 2 :

Find the ratio of the age of John to David.

Solution :

Age of John  =  17 years

Age of David  =  15 years

Age of John : Age of David  =  17 : 15

Hence, the ratio of the age of John to David is

17 to 15

Question 3 :

Find the ratio of the age of David to John.

Solution :

Age of David  =  15 years

Age of John  =  17 years

Age of David : Age of John  =  15 : 17

Hence, the ratio of the age of David to John is

15 to 17

Question 4 :

Find the ratio of the weight of David to John.

Solution :

Weight of David  =  29 kg

Weight of John  =  31 kg

Weight of David : Weight of John  =  29 : 31

Hence, the ratio of the Weight of David to John is

29 to 31

Question 5 :

Find the ratio of the height of John to David.

Solution :

Height  of John is

=  1m + 36cm

=  100cm + 36cm

=  136 cm

Height of David  =  123 cm

Height of John : Height of David  =  136 : 123

Hence, the ratio of the height of John to height of David is

136 to 123

Question 6 :

Find the ratio of studying time of John to David.

Solution :

Studying time of John  is

=  4 hours

=  4 ⋅ 60 min

=  240 minutes

Studying time of David  =  180 minutes

Studying time --> John : David  =  240 : 180

Studying time --> John : David  =  4 : 3

Hence, the ratio of studying time of John to David is

4 to 3

Question 7 :

Find the ratio of speed of cycling between John and David.

Solution :

Speed of cycling  of John  =  10 kmph

Speed of cycling of David  = 15 kmph

Speed of cycling --> John : David  =  10 : 15

Speed of cycling --> John : David  =  2 : 3

Hence, the ratio of speed of cycling between John and David is

2 to 3

Question 8 :

Find the ratio of playing time of John to David.

Solution :

Playing time of John  =  2 hours

Playing time of David  =  1 hour

Playing time --> John : David  =  2 : 1

Hence, the ratio of playing time of John to David is

2 to 1

Question 9 :

A student has 12 note books and 8 text books. Find the ratio of the note books to text books.

Solution :

No. of note books  =  12

No. of textbooks  =  8

No. of note books : No. of textbooks  =  12 : 8

No. of note books : No. of textbooks  =  3 : 2

Hence, the ratio of notebooks to textbooks is

3 to 2

Question 10 :

The cost of a pen is \$3 and the cost of pencil is \$1.50. Find the ratio of the cost of a pen to pencil.

Solution :

Cost of a pen  =  \$3  =  3 ⋅ 100  =  300 pennies

Cost of a pencil  =  \$1.50  =  1.50 ⋅ 100  =  150 pennies

Cost of a pen : Cost of a pencil  =  300 : 150

Cost of a pen : Cost of a pencil  =  2 : 1

Hence, the ratio of cost of a pen to pencil is

2 to 1

(From question no. 11 to question no.13, please use the information given below)

In a Village of 10,000 people, 4,000 are Government Employees and the remaining are self-employed.

Question 11 :

Find the ratio of the government employees to people of the village.

Solution :

No. of government employees  =  4000

Total no. of people in the village  =  10000

Government employees : Village people  =  4000 : 10000

=  2 : 5

Hence, the ratio of government employees to village people is

2 to 5

Question 12 :

Find the ratio of self employed to people of the village.

Solution :

No. of self employed is

=  10000 - 4000

=  6000

Total no. of people in the village  =  10000

Self employed : Village people  =  6000 : 10000

=  3 : 5

Hence, the ratio of self employed to village people is

3 to 5

Question 13 :

Find the ratio of self employed to government employees.

Solution :

No. of self employed is

=  10000 - 4000

=  6000

No. of government employees  =  4000

Self employed : Government employees  =  6000 : 4000

Self employed : Government employees  =  3 : 2

Hence, the ratio of self employed to government employees is
