In this section let me help you on solving ratio and proportion.
Introduction to ratio and proportion:
Study of ratio and proportion are one of the main basic for mathematics. Here, the ratios are used to study the relationship between the two numbers given. . The symbol used for the proportion are " alpha" .And the symbol used for ratio is ":"
Problems on Ratio and Proportion:
Following example will also help us in Ratio and Proportion
Q.1 A field is 90 m long and 60 m wide. Find the ratio between itsi) breadth and Length
ii)Length and Perimeter
Solution:
1) Breadth: length
60m: 90m
60: 90
60 / 30: 90 / 30 (divide both by 30)
2: 3
ii) Perimeter = 2[length + breadth]
=2[90 + 60]
= 2[ 150 ]
= 300 m
Now length : Perimeter
90 : 300
90 / 30 : 300/30
3 : 10
