In Cross-Product Property, if 2a / 4 = 6a / 12, then
2a (6a) = 4 (12)
6a / 4 = 12 / 2a
2a (12) = 6a (4)
12 + 6a = 2a + 4

In Addition Property, if 2a / 4 = 6a / 12, then
4(12) = 6a (2a)
2a(12) = 6a(4)
2a + 4 / 4 = 6a + 12 / 12
2a - 4 / 4 = 6a - 12 / 12

120s - Q10
In a certain room, there are 28 women and 21 men. What is the ratio of men to women? What is the ratio of women to the total number of people?
Men : women = 21 : 28 = 4:3
Women : total number of people = 28 : 49 = 4 : 7
Men : women = 21 : 28 = 4:7
Women : total number of people = 28 : 49 = 3 : 4
Men : women = 21 : 28 = 3:4
Women : total number of people = 28 : 49 = 4 : 7
Men : women = 21 : 28 = 3:4
Women : total number of people = 28 : 49 = 7 : 4
