enVision Math Common Core 4th Grade Answers Key Topic 10 Extend Multiplication Concepts to Fractions<\/h2>\n

Essential Questions:<\/strong>
\nHow can you describe a fraction using a unit fraction? How can you multiply a fraction by a whole number?
\nAnswer:
\nA fraction can be converted into a unit fraction as explained below:
\nPut the whole number over 1 to turn it into a fraction.
\nEx:
\nThe whole number is: 5
\nThe conversion of 5 into a unit fraction is: \\(\\frac{1}{5}\\)
\nA fraction can be multiplied by a whole number as explained below:
\nStep 1:
\nMultiply across the top number by top number (numerator) and bottom number by bottom number (denominator).
\nStep 2:
\nSimplify your answer by dividing both numerator and denominator by the same number, when applicable.\"Envision<\/p>\n

enVision STEM Project: Light and Multiplication<\/strong>
\nDo Research<\/strong>
\nUse the Internet or other sources to research the words transparent, translucent, and opaque? Write a definition for each word.
\nAnswer:
\nTransparent:
\nIf any material allows all light to pass through it, then it is called “Transparent”
\nTranslucent:
\nIf any material allows some light to pass through it, then it is called “Translucent”
\nOpaque:
\nWhen any material allows no light to pass through it, then it is called “Opaque”<\/p>\n

Journal<\/strong>: Write a Report<\/strong>
\nInclude what you found. Also in your report:
\nPART A:
\nList 1 example of each of the items that are transparent, translucent, or opaque.
\nAnswer:
\nExamples of Transparent items are:
\na. Clean glass
\nb. Water
\nc. Air
\nExamples of Translucent items are:
\na. Frosted glass
\nb. Wax paper
\nc. Smoke
\nd Butter paper
\nExamples of Opaque items are:
\na. Stone
\nb. Metal
\nc. Wood<\/p>\n

PART B:
\nSuppose one-third of each of 5 same-sized posters is covered with opaque paper. What fraction of the posters are not covered by opaque paper? Explain how to use multiplication to find what parts of the posters are not covered by opaque paper?
\nAnswer:
\nIt is given that
\nOne-third of each of 5 same-sized posters is covered with opaque paper
\nNow,
\nThe representation of the 5 same-sized posters with opaque paper is:
\n\"\"
\nNow,
\nFrom the given figure,
\nWe can observe that
\nThe total number of parts are: 5
\nThe number of parts covered with opaque paper is: 3
\nThe number of parts that are not covered with opaque paper is: 2
\nNow,
\nThe fraction of the posters that are covered by the opaque paper = \\(\\frac{The number of parts that are covered with opaque paper}{The total number of parts}\\)
\n= \\(\\frac{3}{5}\\)
\nSo,
\nThe fraction of the posters that are not covered by the opaque paper = \\(\\frac{The number of parts that\u00a0 are not covered with opaque paper}{The total number of parts}\\)
\n= \\(\\frac{2}{5}\\)
\nHence, from the above,
\nWe can conclude that
\nThe fraction of the posters that are not covered by the opaque paper is: \\(\\frac{2}{5}\\)<\/p>\n
