Lauren’s age is 2/3 of kylie’s age. Twelve years ago, Lauren’s age was half of Kylie’s age. How old is Lauren now?

If you have learned pre-algebra and algebra, you can use linear equation 3/2 X-12=2(X-12) to easily solve the variable . If you haven't learned algebra, you can get the answer by drawing a graph:

Lauren's age is 2/3 of Kylie's age, you can draw a graph to represent Kyile and Lauren's age as below. (Kyile has 3 units of age, Lauren has 2 units of age.)

Kylie I------------I------------I------------I

Lauren I------------I------------I

12 years ago, Lauren's age was half of Kyile's age. Hence, Lauren's age -12 = 1/2 (Kyile's age -12).

If you double Lauren's age, then minus twice the number 12, it will equal to Kyile's age minus 12.

Thus 2xLauren's age is 12 years more than Kyile's age.

Adding that information on the graph:

Kylie I------------I------------I------------I

2Lauren I------------I------------I------------I------------I

I 12 I

2Lauren has 4 units of age, kylie has 3 units of age. Hence one unit equals to 12.

Lauren's age is two units of age: 2x12=24
