    Study Notes

    Fractions

    • A fraction is a way to represent a part of a whole.
    • You need to add or subtract fractions when you're dealing with quantities that are not whole units.
    • The example 'drained 1/4 of a quart of gas from a gas tank that had 3/4 of a quart in it' demonstrates subtraction of fractions.
    • 4/10 and 3/10 represent running distances of 4 and 3 units out of 10 units respectively.
    • '7/8 of a stick of butter' means 7 units out of 8 units of a whole stick of butter.
    • '2/5 full' represents a gas tank that is 2 units out of 5 units full.
    • The first step in subtracting fractions with different denominators is to find the lowest common denominator (LCD).
    • The key requirement for adding or subtracting fractions is that they must have the same denominator.
    • Before adding or subtracting fractions with different denominators, you need to find the lowest common denominator (LCD).
    • An improper fraction is a fraction where the numerator is greater than the denominator.
    • Fractions need to have the same denominator for addition or subtraction because it allows you to compare the same parts of the whole.
    • A mixed number is a combination of a whole number and a fraction.
    • After finding the lowest common denominator (LCD) for fractions, you can convert them to equivalent fractions with the LCD.
    • You need to convert mixed numbers to improper fractions before adding or subtracting because it makes it easier to perform the operation.
    • The purpose of finding the lowest common denominator before adding or subtracting fractions is to make it possible to compare the same parts of the whole.
    • According to Republic Act 8293, Section 176, permission is required to reproduce any part of the material.
    • The consequence of reproducing any part of the material without permission is copyright infringement.
    • The government is responsible for setting appropriate fees for using copyrighted materials.
    • You need to get permission before using any material beyond the scope of the module.
    • It is emphasized that permission is required for using any part of the material.
    • The creator of the material may claim copyright for using any part of the material.

    Art

    • The medium of painting that is a mixture of ground pigments and an aluminous and colloidal vehicle, either egg, gum or glue, and is usually done on a wooden panel is tempera.
    • The medium of painting that possesses color that only covers the surface of light, gives no glazed effect, and most closely resembles dry pigment is fresco.
    • A painting that is made up of layers of pigments applied onto a surface is a two-dimensional art form.
    • The medium of painting where the pigments are mixed in oil, and the surface used is usually canvass although other surfaces like wood, paper, and metal may be used is oil painting.
    • The medium of painting where the pigments are mixed with water and applied to fine, white paper in very thin layers is watercolor painting.
