To determine which numbers should be grouped in the expression 18.35 + 5 + 11.65, let's evaluate each option:
A. (18.35 + 5) + 11.65
Here, you’re adding 18.35 and 5 first, which equals 23.35, and then adding 11.65.
Calculation: 23.35 + 11.65 = 35.
B. (18.35 + 11.65) + 5
This groups 18.35 and 11.65 first. Adding them gives 30, then adding 5 results in:
Calculation: 30 + 5 = 35.
