12 1/2 - 9 1/4= What is the answer to this question?

First you would convert them to improper fractions with common denominators.

12 1/2 >>>> 25/2

9 1/4 >>>>>> 37/4

to get a common denominator, you would multiply 25/2 by 1/2 to get 50/4.

50 - 37 = 13

so your answer would be 13/4

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
