15/3 - 4/3 = 11/3
15/3 = 5
Hmm, this is a tricky one. I'll do my best, though.
Well, we know that __ + __ = 36 and that one of the 2 numbers is double the other. We'll use x to be one number, and we'll use 2x to be double the number (because when you double x, you'll have 2x). And we know that we add them, right?
x + 2x = 36. Now this is making sense! Just solve it!
x+2x=36
3x=36
x=12 But don't forget, that's only the age of the younger sister. The older sister is double the age of x, or 12. What is 12 doubled? 24.
<em>The age of the two sisters is</em><em> 12 </em><em>&</em><em> 24</em><em>.</em>
