Question

5/12 of the population of a city are women. 2/9are children rest are men... Find the fraction

Answer 1

Answer:

LCM of 12 and 9 is 36

5 × 3

------- = 15/36

12 × 3

2 × 4

------- = 8/36

9 × 4

Let x be fraction of men in the city

15/36 + 8/36 + x = 36/36

23/36 + x = 36/36

(Transversing 23/36 to RHS)

x = 36/36 - 23/36

x = 36 - 23/36

x = 13/36

13/36 of the city are men

5/12 of the city are women

2/9 of the city are children
