This video will show you how to solve simple ratio problems by doing an equivalent ratio. In example 1, the ratio of boys to girls in a class is 3:2. If there are 18 boys in the class how many girls are in the class?
To do this write the ratio down and put the 18 under the boys side of the ratio. Figure out what the ratio has to be multiplied by. Do this by dividing 18 by 3 to give 6. Then multiply the other side of the ratio by this number to give 12 girls.

The major cause of the decrease of the female birth ratio in India is considered to be the violent treatments meted out to the girl child at the time of the birth. The Sex Ratio in India was almost normal during the phase of the years of independence, but thereafter it started showing gradual signs of decrease. Though the Sex Ratio in India has gone through commendable signs of improvement in the past 10 years, there are still some states where the sex ratio is still low and is a cause of concern for the NGO organizations. One of the states which is showing a decreasing trend in the population of women 2011 and is a cause of concern is Haryana. The state of Haryana has the lowest rate of sex ratio in India and the figure shows a number of 877 of females to that of 1000 of males.

Comparison of 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.
Example 1 : Length and breadth of a rectangular field are 50 m and 15 m respectively. Find the ratio of the length to the breadth of the field.
