A typical ancestry report might look like this, Country Approximate amount Algeria 1 20 Morocco 1 100 Benin 1 25 Cameroon 7 100 Spain 7 50 Portugal 1 4 Italy 6 25 England 1 5 Order the countries from lowest to highest by finding a common denominator.

Given, Country Approximate amount Algeria 1 20 Morocco 1 100 Benin 1 25 Cameroon 7 100 Spain 7 50 Portugal 1 4 Italy 6 25 England 1 5 First we need to find the LCM of the denominators as the denominators are not equal. LCM of 20 , 100 , 25 , 100 , 50 , 4 , 25 , 5 is , 2 20 , 100 , 25 , 100 , 50 , 4 , 25 , 5 2 10 , 50 , 25 , 50 , 25 , 2 , 25 , 5 5 5 , 25 , 25 , 25 , 25 , 1 , 25 , 5 5 1 , 5 , 5 , 5 , 5 , 1 , 5 , 1 1 , 1 , 1 , 1 , 1 , 1 , 1 , 1 Thus, LCM of 20 , 100 , 25 , 100 , 50 , 4 , 25 , 5 = 2 × 2 × 5 × 5 = 100 Now, each fraction is converted to its equivalent fraction with denominator equal to the LCM. Thus, 1 20 = 1 × 5 20 × 5 = 5 100 1 100 = 1 × 1 100 × 1 = 1 100 1 25 = 1 × 4 25 × 4 = 4 100 7 100 = 7 × 1 100 × 1 = 7 100 7 50 = 7 × 2 50 × 2 = 14 100 1 4 = 1 × 25 4 × 25 = 25 100 6 25 = 6 × 4 25 × 4 = 24 100 1 5 = 1 × 20 5 × 20 = 20 100 We know that when denominators are equal, we need to compare the numerators. Here, 1 < 4 < 5 < 7 < 14 < 20 < 24 < 25 Hence, the order of the countries from lowest to highest, Morocco, Benin, Algeria, Cameroon, Spain, England, Italy, Portugal.

Given, Country Approximate amount Algeria 1 20 Morocco 1 100 Benin 1 25 Cameroon 7 100 Spain 7 50 Portugal 1 4 Italy 6 25 England 1 5 We know that to convert fraction into percentage, we multiply the fraction by 100 . Thus, 1 20 = 1 20 × 100 = 5 % 1 100 = 1 100 × 100 = 1 % 1 25 = 1 25 × 100 = 4 % 7 100 = 7 100 × 100 = 7 % 7 50 = 7 50 × 100 = 14 % 1 4 = 1 4 × 100 = 25 % 6 25 = 6 25 × 100 = 24 % 1 5 = 1 5 × 100 = 20 % We know that when denominators are equal, we need to compare the numerators. Here, 1 % < 4 % < 5 % < 7 % < 14 % < 20 % < 24 % < 25 % Hence, the order of the countries from lowest to highest, Morocco, Benin, Algeria, Cameroon, Spain, England, Italy, Portugal.

The Chinese zodiac follows a $12 -$ year cycle, with each year represented by one of the $12$ animals from the Chinese zodiac. Your birth year corresponds to one of these $12$ animals. If average life expectancy is approximately $80$ years, approximately what fraction of a person's lifetime will be spent in the years of their Chinese zodiac sign?

Many of China's people work in big cities and travel back to their home town for Spring Festival. For some people, it is the only time in the year when they will visit their families. The modes of transportation taken by these people break down as follows:

$\frac{7}{60}$ by rail, $\frac{3}{200}$ by boat, $\frac{1}{50}$ by airplane, $\frac{5}{6}$ by road.

Rank the modes of transportation from most to least popular.
