Final answer:
1230 days make up 175 weeks with a remainder of 5 days, which means there are five extra days not completing a full week.
Step-by-step explanation:
One week consists of seven days.
To find out how many weeks are in 1230 days, divide 1230 by 7. 1230 ÷ 7 equals 175 weeks with a remainder of 5.
This remainder represents the number of days left over after accounting for the full weeks, which is less than a full week's worth of days.
In this context, if 1230 days were to be grouped into full weeks, there would be 175 full weeks and an extra 5 days that do not fit into the week structure.
