Respuesta :

Ellen sold 27 magazines, Patty sold magazines and Rajel sold 24.

Answer:

first blank: 27

second blank: 12

third blank: 24

Step-by-step explanation:

Mark sold 9 magazines

For every magazine Mark sold, Ellen sold three magazines. So Ellen sold 3*9 = 27 magazines

For every three magazines Mark sold, Patty sold four magazines. Then the following proportion must be satisfied:

3 magazines sold by Mark / 9 magazines sold by Mark = 4 magazines sold by Patty / x magazines sold by Patty

x = 4*9/3 = 12  

The ratio of the number of magazines Mark sold to the number of magazines Rajel sold is 3:8. That is:

3 magazines sold by Mark / 9 magazines sold by Mark = 8 magazines sold by Rajel / x magazines sold by Rajel

x = 8*9/3 = 24
