##### About 6 Maths Chapter 12

In 6 Maths Chapter 12 Ratio and Proportion, we will study about various types of ratios and their conversions into percentages, fractions or decimals. We compared the two quantities in terms of ‘how many times’. This comparison is known as the Ratio. We denote ratio using symbol ‘:’.  Two quantities can be compared only if they are in the same unit. If they are not same convert them into same units. For example in the following questions the quantities are in the same units.

1. Cost of a toffee is ₹0.50 and cost of a chocolate is ₹10. Find the ratio of the cost of a toffee to the cost of a chocolate.
2. Mayank takes 15 minutes to reach school from his house and Shikhar takes one hour to reach school from his house. Find the ratio of the time taken by Mayank to the time taken by Shikhar.
3. In a school, there were 73 holidays in one year. What is the ratio of the number of holidays to the number of days in one year?

Note: We can get equivalent ratios by multiplying or dividing the numerator and denominator by the same number.

#### 30 students in a class, like football, 12 like cricket and remaining like tennis. Find the ratio of number of students liking football to number of students liking tennis.

Total number of students = 30
Number of students like football = 6
Number of students like cricket = 12
Thus number of students like tennis
= 30 – 6 – 12
= 12

The ratio of students like football that of tennis
= 5/12
= 1 : 2

#### यदि 7 मी कपड़े का मूल्य ₹1470 हो तो 5 मी कपड़े का मूल्य ज्ञात कीजिए।

7 मीटर कपड़े का मूल्य
= ₹1470
1 मीटर कपड़े का मूल्य
= 1470/7 = ₹210
5 मीटर कपड़े का मूल्य
= ₹210 x 5
= ₹1050

अतः, 5 मी कपड़े का मूल्य ₹1050 है।

#### एकता 10 दिन में ₹3000 अर्जित करती है। 30 दिन में वह कितना अर्जित करेगी?

एकता 10 दिन में अर्जित करती है
= ₹3000
एकता 1 दिन में अर्जित करती है
= 3000/10
= ₹300
30 दिन में अर्जित करती है
= ₹300 x 30
= ₹9000

अतः, एकता 30 दिन में ₹9,000 अर्जित करती है।

#### If it has rained 276 mm in the last 3 days, how many cm of rain will fall in one full week (7 days)? Assume that the rain continues to fall at the same rate.

Rain in 3 days
= 276 mm
Rain in 1 day
= 276/3
= 92 mm
Rain in 7 days
= 92 x 7
= 644 mm

Thus, the rain in 7 days is 644 mm.

#### Cost of 5 kg of wheat is ₹91.50. What will be the cost of 8 kg of wheat?

Cost of 5 kg of wheat
= ₹91.50
Cost of 1 kg of wheat
= 91.50/5
= ₹18.30
Cost of 8 kg of wheat
= ₹18.30 x 8
= ₹146.40

#### शाइना 3 महीने का किराया ₹15000 देती है। उसे पूरे वर्ष का किराया कितना देना होगा यदि वर्ष भर किराया समान रहे?

3 महीने का किराया
= ₹15000
1 महीने का किराया
= 15000/3
= ₹5000
12 महीने का किराया
= 5000 x 12
= ₹60,000

अतः, उसे पूरे वर्ष का किराया ₹60,000 देना होगा।

#### 4 दर्जन केलों का मूल्य ₹180 है। ₹90 में कितने केले ख़रीदे जा सकते हैं?

4 दर्जन केलों का मूल्य
= ₹180
इसलिए, 48 केलों का मूल्य
= ₹180
[4 दर्जन = 4 x 12 = 48] ₹180 में ख़रीदे गए केले
= 48
₹1 में ख़रीदे गए केले
= 48/180
=4/15
₹90 में ख़रीदे गए केले
= 4/15 × 90
=24

अतः, ₹90 में 24 केले ख़रीदे जा सकते हैं।
