Question

(16a/b)-(5b/4) Perform the indicated operation

Answer 1

\[\frac{ 16a }{ b}-\frac{ 5b }{ 4 }\]
Did I rewrite that correctly?

Answer 2

Yes thats correct

Answer 3

So, you need to find a common denominator. Since b is a variable, you'll want to just multiply both denominators. To do that, you need to multiply the top and the bottom by the same thing (which is like multiplying by 1). Once you get a common denominator, you can combine the fractions and simplify, if possible.
