You only did the last one wrong, (3/4) times 2 is 3/2. 3/2 - 1/2 is 2/2 or 1.

Step-by-step explanation:
IF THERE ARE FIVE PIECES TO BE SHARED AND EVERYONE MUST HAVE AN EQUAL SHARE THEN EACH PERSON SHOULD GET HALF A PIZZA WHICH IS 1/2. BETWEEN 0 AND 1 IS WHAT THE FRACTION 1/2 WE BE BETWEEN.
8-(r+9)-7 = 9
First, distribute the (-) sign! ^^
8-r-9-7=9
Calculate the numbers! ^^
-8-r = 9

-r = 17
Move the sign! ^^
r = -17
^ this is your answer :)
