Question

Leah has 5 times as many marbles as Karen.Together they have 72 marbles.How many marbles does Leah have

Answer 1

If possible, assign a variable to the value the problem wants you to find.  Let x=number of Leah's marbles.

 

"Leah has 5 times as many marbles as Karen"    means   x = 5*(Karen's marbles)   or  Karen has x/5

"Together they have 72 marbles"    means     x + x/5 = 72

               5x + x = 360      (everything multiplied by 5)

                    6x = 360

                     x = 60  

Answer 2

Karen has = x marbles

 

Leah has 5x marbles

 

Together have = 72 marbles.  Then:      x + 5x = 72

 

                                                             6x=72

 

                                                               x= 12

 

Finally:                      Leah has 5*12= 60 marbles.

Answer 3

First you have to find the numbers that add up to 72 that would make the equation  5x+x=72 true.

If Karen has 12 marbles, and Leah has 5 times what Karen does, then Leah has 60 marbles. Which in total makes 72 marbles.
