Study Notes

Fractions

  • Three dimes is equivalent to 30 cents.
  • 30 cents is 3/10 of a dollar.
  • 30 cents is 30% of a dollar.

Perpendicular Lines

  • A line that intersects another line at a right (90-degree) angle is called a perpendicular line.

Fractions

  • To determine how many times a fraction goes into a whole number, divide the whole number by the fraction.
  • In this case, 1 divided by 2/5 equals 5/2 or 2.5.

Mixed Numbers

  • To change a mixed number into an improper fraction:
    • Multiply the whole number by the denominator of the fraction.
    • Add the numerator to the product.
    • The denominator of the improper fraction is the same as the denominator of the original fraction.
  • 3 1/3 is equal to 10/3.

Ordering Numbers

  • A negative number is always less than a positive number.
  • Integers are whole numbers, positive or negative.
  • 1/3 is not an integer because it is a fraction.

Associative Property of Addition

  • This property states that the sum of three or more numbers remains the same regardless of how the numbers are grouped.
  • Example: (2+3)+5 = 2+(3+5)

Area

  • The area of a rectangle is found by multiplying its length and width.

Subtraction

  • The difference between 100 million and 58 million is 42 million.

Factors

  • Factors are numbers that divide evenly into another number.
  • The factors of 21 are 1, 3, 7, and 21.
  • The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

Greatest Common Factor

  • The greatest common factor (GCF) is the largest factor that is shared by two or more numbers.
  • The greatest common factor of 21 and 48 is 3.

Inequality

  • The product of 1 and 3 is 3.
  • The sum of 1 and 3 is 4.
  • An inequality uses symbols to compare numbers or expressions.
  • The product of one and three is less than the sum of one and three can be written as: 1 x 3 < 1 + 3

Addition Equations

  • To solve for m, subtract 2320 from both sides of the equation.
  • Therefore, m = 2440

Subtraction Equations

  • To solve for n, add $8.75 to both sides of the equation.
  • Therefore, n = $18.30

Multiplication Equations

  • To solve for p, divide both sides of the equation by 35.
  • Therefore, p = 26

Adding Fractions

  • To add fractions with like denominators, add the numerators and keep the same denominator.
  • 3/5 + 1/5 = 4/5

Subtracting Fractions

  • To subtract fractions with the same denominator, subtract the numerators and keep the same denominator.
  • 9/11 - 3/11 = 6/11

Multiplying Fractions

  • Multiply the numerators and multiply the denominators
  • 3/5 x 4/7 = 12/35

Division

  • Dividing by a number is equivalent to multiplying by the reciprocal of that number.
  • To find the reciprocal of a fraction, flip the numerator and the denominator.
  • Therefore, 2/5 divided by 2/5 is the same as 2/5 multiplied by 5/2.
  • 2/5 x 5/2 = 1.

Geometry

  • MC is a segment.

  • PM is a ray.

  • FH is a line.

  • A segment is a part of a line that has two endpoints.

  • A ray has one endpoint and extends infinitely in one direction.

  • A line extends infinitely in both directions.
