Rounding Word Problems

Rounding Word Problems Rounding numbers coverts large numbers and decimal numbers to simpler forms which are then useful to solve or express in a given question. This concept is commonly used in many word problem and different calculations. Rounding to the tenths place is rounding of a decimal number to the nearest one decimal space. Rounding to the hundredths place is rounding a decimal number to the nearest two decimal spaces. Rounding to the thousandths place is rounding a decimal number to the nearest three decimal spaces and so on. Example 1: The price of each book is $ 15.78. If the shopkeeper sold 13 copies. Find the total money earned by the shopkeeper. Solution: Price of each book = $ 15.78. Number of copies sold by the shopkeeper = 13. The money earned by the shopkeeper = 13 * 15.78 = $ 205.14. Rounding the decimal number to the nearest whole number. Hence the money earned by the shopkeeper = $ 205. Example 2: There are 15 children in the class. 7 of them buy cupcakes and the remaining buy cookies. Each cookie costs $ 1.89 and cupcake costs $2.24. How much did the class spend (round to a whole number)? Solution: Price of each cookie = $ 1.89. Price of each cupcake = $ 2.24. Number of students brought cupcakes = 7 Number of students brought cookies = 8. Amount spent on cupcakes = 7 * 1.89 = $ 13.23 Amount spent on cookies = 8 * 2.24= $ 17.92 The total amount spent = $ 31.15 (Rounding the decimal) Hence, total amount spent = $ 31.

How to Study - Tips and Tricks That Work BobbiM Sep 23, 2015 Sometimes its just the basics that you need to do if you want to learn how to study for exams or tests.  Nothing fancy, nothing special just the basics.  And nothing is more basic than learning how to take good notes and creating note cards that have all the facts, details and specific information that you need for whatever the course may be.  This is really the ultimate way to study for anything to do with spelling or history!  Its cheap, fast, easy and concise and most of all it works! Whats this special tip?  Note cards.Yes, note or index card studying. The best way to do this is throughout the semester as you study at night or at the end of a chapter as you prep for a test or exam.  Ive seen some do it just for finals but its a mind numbing, exhausting and time consuming process if you have to crank out an entire semesters worth of note cards for most courses.  And it takes longer then to do it than it would if you did it as you were going through the chapter initially.  So to save your brain cells for other things and to save time, create your note cards as you move through each topic, chapter, book or lesson.  You will be so glad that you did it that way! Yes, there are fancier ways and more technologically advanced ways of accomplishing the same things.  However, Ive yet to see one that is any faster, easier or less costly.  Nor is there one that I know of that is more effective.  You see this tip requires you to identify the fact, word or concept.  Then you have to write it down and check what you wrote.  So its THREE TIMES that you are going over that one point without even knowing that you are drilling it in that often already.
