Lesson 19<br />PROBLEM SOLVING INVOLVING DIVISION OF WHOLE NUMBERS<br />Objectives <br />After this lesson, the students are expected to:<br />solve the given problem critically;<br />follow the steps in problem solving ;<br />apply the division of whole numbers in solving mathematical problem.<br />Like the first three operations, the division operation is very usable to our daily lives. We use also this operation to solve some problems. Take a look and study the examples given below<br />1745615278765<br />ExampleYou are the manager of a ski resort and noticed that during the month of January you sold a total of 111,359 day ski tickets. What was the average number of tickets that were sold that month?<br />SolutionSince there are 31 days in January, we need to divide the total number of tickets by 31<br />Answer: The ski resort averaged 3,589 ticket sales per day in the month of January. 3589 31 | 111259 93 31 x 3 = 93 182 111 - 93 = 18 and drop down the 2 155 31 x 5 = 155 275 182 - 155 = 27 and drop down the 5 248 31 x 8 = 248 279 275 - 248 = 27 279 31 x 9 = 279 0<br />Another example<br />Courtney is hanging glow in the dark stars in each room of his house. If there are 160 stars in the box and she wants 16 in each room, how many rooms can she hang stars? <br />Solution <br />Since there are 160 stars in the box and she wants 16 in each room. And the problem is asking for how many stars in each room will be?<br /> 10<br />16 16016x1=16 1616-16=0 0016x0=0 00<br /> 0<br />Answer: Courtney can hang her 160 stars in 10 rooms<br />-535351-266700WORKSHEET NO. 19<br />NAME: ___________________________________DATE: _____________ <br />YEAR & SECTION: ________________________RATING: ___________<br />Analyze and solve the following problems.<br />Jacinta has 5 pennies in a jar.
