3+3 = 6
You add the two numbers together as the denominator and put one of the original numbers in the numerator. Example: The ratio of girls to boys in Class A is 2:3. Total number of children in the ratio: 2+3=5 You want to organize the information into: # of girls 2 ________________ = _____ Total # of children 5
The ratio of girls to boys in this case would be 10:1
It is already in its simplest ratio because 17 is a prime number but if it were 7 boys to 21 girls then the ratio would be 1 to 3
If the ratio of boys to girls is 12 to 3, then the total ratio is 12 + 3 = 15. To find how many girls are in the class, we divide the number of girls by the total ratio, 24 / 15 = 1.6. This means there are approximately 1.6 girls in the class. However, since we can't have a fraction of a girl, we can conclude that there are 2 girls in the class.

Probability
The number of children in the average American family has dropped from 2.5 to 1.3. On average there are more boys in an American family than girls. In 2002 about 95,000 more boys were born than girls. The mother's age may influence this phenomenon: older mothers about 40 have fewer boys than girls. Teen mothers experience the opposite. Chinese mothers have the highest ratio of boys to girls.
