Let's represent the ratio of Olivia's and Sylvia's allowances as 2x:3x.
We know that Sylvia gets $21 one week, which represents 3x. So, we can set up the equation 3x = 21.
To find x, we divide both sides of the equation by 3. 3x/3 = 21/3, which simplifies to x = 7.
Now, we can find Olivia's allowance by multiplying her ratio (2x) by x. Olivia gets 2 * 7 = $<<2*7=14>>14. Answer: \boxed{14}.
