The fraction which produce an equivalent fraction with a rational denominator is 
Explanation:
The equation is 
To find the rational denominator, let us take conjugate of the denominator and multiply the conjugate with both numerator and denominator.
Rewriting the equation, we have,

Multiplying, we get,

Simplifying the denominator, we get,

Subtracting, the values of denominator,

Dividing the numerator and denominator,

Hence, the denominator has become a rational denominator.
Thus, the fraction which produce an equivalent fraction with a rational denominator is

<em>Thanks</em>
B^-2/ab^-3 = b^-2/b^-3 x 1/a = b^[-2-(-3)] x 1/a = b x 1/a = b/a
Do 21 divided by 2 and you’ll get 10.5 so the original price was $10 and 50 cents
