Lesson, , 1, , Reading Decimal Numbers, through Ten Thousandths, , What’s In, In the previous module, you learned the concept of Place Value. To read, write, and order decimals properly, you need to master what all the decimal place values, are. A place value is the position of the digit in a number. It determines the value, that the number holds. For an easy understanding, a place value chart is used., , Place Value, , Thousands, , Hundreds, , Tens, , Ones, , Decimal Point, , Tenths, , Hundredths, , Thousandths, , Ten, Thousandths, , Below is the place value chart. Study it very carefully., , Value, , 1,000, , 100, , 10, , 1, , , , 1, , 01, , 001, , 0001, , The chart illustrates the first four positions to the left and the first four, positions to the right of the decimal point. It indicates the place value and value of, a number based on the position of the digit., , 4, , CO_Q2_Math5_Module2

What’s New, There are things on earth that are very tiny which cannot be seen through, our naked eyes, like the atom or the Coronavirus. These things, are measured and expressed in decimal numbers. For example,, the calculated radii of a hydrogen atom are 53 picometer which, is equal to 0.000000053 millimeter., On the other hand, the Coronavirus diameter is, approximately from 60 to 140 nanometer or 0.00006 millimeter to, 0.00014 mm. Also, the value of money can be expressed in decimal, numbers. For example, the exchange rate of a peso to a dollar on May, 18, 2020, amounted to P 50.5880 per dollar., , These are only few of the many instances that talk about or involve decimals., Study and familiarize the table above., Clearly, there is a need for us to study and learn decimal numbers. With this,, it is important that we know how to read decimals. To help us read decimal numbers,, a step-by-step process is introduced in the next portion of this module., Are you ready now? You can have an extra sheet of paper and pen with you, for you to practice as you follow through the steps for each guided example., 7, , CO_Q2_Math5_Module2
Page 12 :
What Is It, In this lesson, you will learn about reading decimal numbers., For this purpose, we will take the peso-dollar exchange rate given in the, previous part. According to the table from Bangko Sentral ng Pilipinas (BSP), as of, May 18, 2020, the peso-dollar exchange rate is Php 50.5880 to a dollar., How do you read 50.5880? Do you know?, Here is the step-by-step process:, Step 1: Write the digits in the appropriate boxes of the place value, , Hundredths, 0.01, , Thousandths, 0.001, , Ten, Thousandths, 0.0001, , 0, , Tenths, 0.1, , Ones, , 5, , Decimal, Point, , Tens, , 50.5880, , Hundreds, , Thousands, , chart., , 5, , 8, , 8, , 0, , , , Step 2: Read the number to the left of the decimal place as whole, number., 50 is read as fifty., Step 3: Read the decimal point as “and”., 50. is read as fifty and., Step 4: Read the number to the right of the decimal place as whole, number., 5 880 is read as five thousand eight hundred eighty., Step 5: When you’re done reading the number to the right of the, decimal point, say the place value of the last digit., In 5 880, the last digit is 0 and its place value is ten thousandths. So,, it will be read as five thousand eight hundred eighty ten, thousandths., , 8, , CO_Q2_Math5_Module2
Page 13 :
Therefore, 50.5880 will be read as fifty and five thousand eight hundred, eighty ten thousandths., Here is another example for you to better understand the topic. Please, consider the situation below., Every, Friday,, teacher, Mary Meldred Normor rides her, car from her residence in Brgy., Malajog heading to Calbayog City, Hall. Based on the Google Map,, she finds its distance to be 16.3, km if she travels via the PanPhilippine Highway., In the above situation, how will you correctly read the distance travelled by, teacher Mary Meldred Normor?, To read the decimal number 16.3, the following steps must be followed:, , Ten, Thousandths, 0.0001, , Thousandths, 0.001, , Hundredths, 0.01, , 6, , Tenths, 0.1, , Ones, , 1, , 16.3, , Decimal, Point, , Tens, , Hundreds, , Thousands, , Step 1: Write the digits in the appropriate boxes of the place value chart., , 3, , Step 2: Read the number to the left of the decimal place as whole number., 16 is read as sixteen., Step 3: Read the decimal point as “and”., 16. is read as sixteen and., Step 4: Read the number to the right of the decimal place as whole number., 3 is read as three., Step 5: When you’re done reading the number to the right of the decimal point, say, the place value of the last digit., Since 3 is the only digit to the right of the decimal point, we will, consider it the last digit and we will read its place value which is tenths., Thus, we read it as three tenths., Therefore 16.3 will be read as Sixteen and three tenths., 9, , CO_Q2_Math5_Module2
Page 14 :
Suppose the given decimal is 0.15. Take note that the whole number part of, the decimal is 0. In this case, we proceed from Step 1 directly to Step 3 without, performing Step 2; thus, we have:, , , , 5, , Ten, Thousandths, 0.0001, , 1, , Thousandths, 0.001, , Hundredths, 0.01, , Decimal, Point, , Ones, 0, , Tenths, 0.1, , 0.15, , Tens, , Hundreds, , Thousands, , Step 1: Write the digits in the appropriate boxes of the place value chart., , Step 4: Read the number to the right of the decimal point as whole number., 15 is read as fifteen, Step 5: When you’re done reading the number to the right of the decimal point, say, the place value of the last digit., In 15, the last digit is 5 and its place value is hundredths. So, it will, be read as fifteen hundredths., Therefore, the decimal number 0.15 will be read as fifteen hundredths., Clearly, when the decimal has no whole number part, you just say the decimal, name., Now that you already know how to read a given decimal number, please be, confident that you can do more. Now, be ready to answer the exercises that follow., Before you finalize your answers, make sure that you have a pen and clean, extra sheet of paper with you to write on. Do not make any unnecessary writings in, this module., , 10, , CO_Q2_Math5_Module2
