Chapter 8: Problem 20

Complete. 623 days = _______wk

Short Answer

Expert verified
623 days is equal to 89 weeks.

Step by step solution

01

Determine the number of days in one week

A standard week is comprised of 7 days. This is fundamental to solving the problem.
02

Set up the division

To convert days to weeks, divide the total number of days by the number of days in a week. So, divide 623 by 7: 623 Days 梅 7 Days/Wk = Total Weeks
03

Perform the division

Calculate the division: 623 梅 7 = 89
04

Verify the result

To ensure the accuracy of the division, multiply the result by 7 to check if it equals 623. 89 脳 7 = 623

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

division
Division is a fundamental arithmetic operation, just like addition, subtraction, and multiplication. It is essentially splitting a number into equal parts. For example, if you have 10 apples and you want to distribute them into 2 groups equally, you divide 10 by 2 to find out that each group gets 5 apples.
In the provided exercise, we need to divide the number of days (623) by the number of days in a week (7). This helps us determine how many weeks are contained within those 623 days.
  • Numerator: The number on top (the number of days: 623).
  • Denominator: The number at the bottom (the number of days in a week: 7).
Thus, 623 梅 7 = 89, meaning there are 89 weeks in 623 days. Division gives us a precise way to convert quantities and helps in understanding ratios and proportions.
multiplication
Multiplication is another fundamental arithmetic operation used to add groups of numbers together quickly. For instance, if you have 3 groups of 4 apples each, you can multiply 3 by 4 to get 12 apples in total.
In the context of our exercise, we use multiplication for verification. After converting 623 days into weeks (89 weeks), we multiply 89 weeks by the 7 days in each week to check if it equals the original 623 days.
  • Multiplicand: The number of weeks (89).
  • Multiplier: The number of days in each week (7).
Therefore, 89 脳 7 = 623. This confirms that our division was correct. Multiplication helps in repeated addition and confirms accuracy in reverse operations like division.
weeks in a year
A year typically has 52 weeks. This is important for understanding larger timescales. A regular year has 365 days. When you divide these days by the 7 days in a week, you get approximately 52 weeks.
Sometimes, knowing the number of weeks in a year helps when planning activities, schedules or understanding longer durations.
  • For example, dividing 365 days by 7, like this: 365 梅 7 鈮� 52 weeks.
Similarly, a leap year has 366 days, slightly more than 52 weeks:
  • Leap year: 366 days 梅 7 days/week 鈮� 52.14 weeks.
Knowing this helps in converting larger blocks of time, such as months and years, into weeks for easier comprehension and planning.
