Answer: If you're looking for the sum of the equation, it's 9.57.
If you're looking for a better way to add it. It's this. (1.7 + 5.3) + 2.57.
Step-by-step explanation: The reason for my answer is quite simple. Since 1.7 and 5.3 add up to 7, all you need to do is add 7 and 2.57. That way, it's much easier to get the answer 9.57
