Answer:
Option 4: -6.1 - (-3.13)
Step-by-step explanation:
Let's solve each option individually to see if -2.97 fits as the solution:
-6.1 - 3.13 = -9.23
-6.1 - (-31.3) = 25.2
-0.61 - (-3.13) = 2.52
-6.1 - (-3.13) = -2.97
As you can see, -2.97 is the answer to Option 4.
So, the decimal -2.97 is the solution to the subtraction problem in Option 4.
