In a class there are 20 boys and 15 girls. The ratio of boys to girls is:
To find the ratio of boys to girls, we simply put the number of boys first, followed by the number of girls. So, it's 20 : 15. However, to simplify the ratio, we can find the greatest common divisor (GCD) of 20 and 15 and divide both numbers by it:
To find the ratio of boys to girls, we simply put the number of boys first, followed by the number of girls. So, it's 20 : 15. However, to simplify the ratio, we can find the greatest common divisor (GCD) of 20 and 15 and divide both numbers by it:
GCD of 20 and 15 is 5.
Divide both numbers by 5: 20 ÷ 5 = 4, 15 ÷ 5 = 3.
So, the simplified ratio is 4 : 3, which corresponds to option (a).
Divide both numbers by 5: 20 ÷ 5 = 4, 15 ÷ 5 = 3.
So, the simplified ratio is 4 : 3, which corresponds to option (a).

Ratio of Boys to Girls in the Class:
In the class, there are 20 boys and 15 girls. To find the ratio of boys to girls, we can simply divide the number of boys by the number of girls.
Calculation:
- Number of boys: 20
- Number of girls: 15
- Ratio of boys to girls: 20/15 = 4/3
Therefore, the correct ratio of boys to girls in the class is 4 : 3.
Explanation:
The ratio of boys to girls is a comparison of the number of boys to the number of girls in the class. In this case, for every 4 boys, there are 3 girls. This means that there are more boys than girls in the class.
Conclusion:
The correct ratio of boys to girls in the class is 4 : 3, which means that for every 4 boys, there are 3 girls. This ratio helps us understand the distribution of boys and girls in the class and is an important concept in mathematics.
