Answer:
Option (1)
Step-by-step explanation:
-8.3+9.2-4.4+3.7 john has used his first step as -8.3+9.2+4.4+3.7.
He has use additive inverse as their is no information is given about the additive inverse -4.4 can not be converted +4.4 .this is his incorrect step .
So, the correct steps are
-8.3+9.2-4.4+3.7
= (-8.3-4.4)+(9.2+3.7)
= -12.7+12.9
= 0.2
Hence, there is need to change the step !.
Hence, the correct answer is 1.
Additive inverse; you can't just take -4.4 and make it positive.
