Answer:
-22/3
Step-by-step explanation:
I'm assuming you want the improper fraction of -7 1/3.
Multiply the denominator of 1/3 (which is 3) by -7, which should give you -21. Add the remaining of the numerator of the fraction, (which is 1) to get -22. Put that over 3, and you get -22/3.
here's the work:
-7 1/3
= -(21+(-1))/3
=-22/3
First determine how many adults are at the park.
28-12=16 adults
If 6 children remain at the park after 3pm, that means there are 6 children left
12-6=6
To determine how many adults are left you must figure out how many left.
8-6=2 adults missing
If 2 adults left at 3pm we can subtract that from the total number of adults
16-2 = 14 adults left at the park.
Hope I could help you and good luck. :)
