Explain, step by step, how to arrive at a single rational number to represent the following expression. Show both a written explanation and the related math work for each step. 1 - 3/4 + (-12 1/4)

-30

Step-by-step explanation:

first you should complete the equition of bracket

1-3/4+(-121/4)

= 1-3/4+(-30.25)

= 1-0.75+(-30.25)

=0.25+(-30.25)

=-30

hence the right answer is -30 :)
