To solve the expression –6.1 + 1.7, you can simply add the two numbers together.
–6.1 + 1.7 = –4.4
So the correct answer is –4.4.
To solve this problem, you need to subtract 1.7 from -6.1. When subtracting, you change the sign of the number you are subtracting and then add it to the other number. So, in this case, you would change the sign of 1.7 to -1.7 and then add it to -6.1.
-6.1 + (-1.7) = -7.8
Therefore, the answer is -7.8.
