Question about Homework
We want to divide the top and bottom numbers by the largest possible number to make the numerator and denominator the smallest possible. We can determine that number by factoring both 192 000 and 650 and see what the biggest common factor is. Another approach is to simplify it step by step.
Let's try the step-by-step method.
Since both end in 0, let's divide both by 10.
19 200 : 65
Since they both end with 0 or 5, we can divide both by 5
3 840 : 13
Since 13 is prime (its only factors are 1 and 13) and 13 doesn't go evenly into 3 840, we cannot go any further.

If you enter the ratios using the fraction entry key ( [a b/c] the
results will be displayed as fractions. And when the calculator
displays fractions they are always in their reduced form.
In general, when you are manipulating fractions ( Pi/2 is no a fraction even if you write it as one) you can try to simplify them by looking for the greatest common factor (GCF) of the numerator and denominator. When you simplify by the GCF the fraction that is left is in its reduced form.
