There are 36 people at a party. Suppose 2 3 of the people are men. How many men and women are present in this party?

Total people in the party = 36 Number of men = 2 3 of 36 = 2 3 × 36 = 2 × 12 = 24 Number of women = Total people - Number of men = 36 - 24 = 12 Hence, number of men and women are 24 and 12 respectively.

One-half of the population of a city is of females. 2 7 of them live in slums. What fraction of the people live in slums?

Let total population of a city is 14 x . So number of females = 7 x And, number of females live in slum = 2 7 × 7 x = 2 x So, fraction of people live in slum = 2 x 14 x = 1 7 So, 1 7 fraction of total population live in slum.
