Exploring Decimals Activity 1: FINDING DECIMAL EQUIVALENTS In the course of converting fractions to their decimal equivalents‚ you should have observed the following: Some fractions convert to terminating decimals; others‚ to repeating decimals. In some fractions that convert to a repeating decimal‚ the digits begin repeating immediately; in others‚ one or more digits appear between the decimal point and the repetend. In this activity‚ you will investigate the answers to the following questions:

Exploration of Lacsap’s Fractions The following will be an investigation of Lacsap’s Fractions‚ that is‚ a set of numbers that are presented in a symmetrical pattern. It is an interesting point that ‘Lacsap’ is ‘Pascal’ backwards‚ which hints that the triangle below will be similar to “Pascal’s Triangle”. 1 1 1 1 1 1 1 1 1 1 There are many patterns evident in this triangle‚ for instance I can see that there

Explain the importance of teaching Math and Science in early education.Use theory or theorist applicable. The importance in teaching mathematics and science is of great concern to all levels of education especially in early education. Because early experiences affect later educational outcomes‚ providing young children with research-based mathematics and science learning opportunities is more likely to pay off with increased achievement‚ literacy‚ and work skills in these critical areas

Dewey Decimal Classification The Dewey Decimal Classification (DDC)‚ or Dewey Decimal System‚ is a proprietary library classification system created by Melvil Dewey in 1876.[1] It has been revised and expanded through 23 major editions‚ the latest issued in 2011.[2] Dewey was responsible for all revisions until his death in 1931. A designation number‚ such as Dewey 16 for the 16th edition‚ is given for each revision. A library assigns a DDC number that unambiguously locates a particular volume

IB Maths SL TYPE I Lacsap’s Fractions Portfolio Lacsap’s fraction Introduction: Lacsap’s fraction is a symmetrical triangle that has the following pattern in the first five rows The shape is similar to Pascal triangle. It has the same quantity of symmetrical triangle as Pascal triangle. And Lacsap is the inverse alphabet order of Pascal. These make me think about Pascal triangle and I made an assumption that elements in Lacsap triangle may have the same relationship as in Pascal triangle

Rounding Mixed Decimals to the Nearest Tenth A concept in mathematics that students need to learn in elementary school is to round mixed decimals to the nearest tenth. This essay describes how I would teach this concept to a group of fourth grade students. To begin‚ I would identify the prerequisite skills that students need in order to master this concept. First the students need to understand place value of whole numbers and decimals; this is necessary because rounding can affect the amount

Mole Fraction Return to Solutions Menu The mole fraction is: moles of target substance divided by total moles involved The symbol for the mole fraction is the lower-case Greek letter chi‚ χ. You will often see it with a subscript: χsolute is an example. Example #1: 0.100 mole of NaCl is dissolved into 100.0 grams of pure H2O. What is the mole fraction of NaCl? Solution: 100.0 g / 18.0 g mol¯1 = 5.56 mol of H2O Add that to the 0.100 mol of NaCl = 5.56 + 0.100 = 5.66 mol total Mole fraction

portray detective work and forensic science have become increasingly popular among readers and enthusiasts. They demonstrate that science is an important tool in answering difficult questions regarding how the tragic assassination of President Kennedy happened for example. Forensic Science is appealing to many people because they want to be detectives to solve problems and puzzles. Today I will focus on how scientific principles embody the study of forensic science but with a main focus on how physicists

in the number system). 1. Decimal Number System The number system that we use in our day-to-day life is the decimal number system. Decimal number system has base 10 as it uses 10 digits from 0 to 9. In decimal number system‚ the successive positions to the left of the decimal point represent units‚ tens‚ hundreds‚ thousands and so on. Each position represents a specific power of the base (10). For example‚ the decimal number 1234 consists of the digit 4 in the units position‚ 3 in the tens position
