Answer:
problem 1: -10.75+(-10.75)= -21.5
problem 2: (−5.375)+(−5.375)+(−5.375)
+(−5.375)= -21.5
Step-by-step explanation:
for the first one is just divided -21.5 by two and added the sum with itself.
for the second I divided -21.5 by 4 and added the sum up 4 times to get -21.5 again.
the equations might look a little too complicated but I hope this helped!
