In grade 8 math, students typically learn a variety of mathematical concepts and skills, such as:

  1. Rational numbers: Students learn to work with fractions, decimals, and percents and understand the relationships between them.
  2. Algebraic expressions: Students learn to manipulate and simplify algebraic expressions, and use them to solve equations and inequalities.
  3. Geometry: Students learn about the properties and relationships of two-dimensional and three-dimensional shapes, including lines, angles, triangles, quadrilaterals, circles, and volume.
  4. Data analysis and probability: Students learn to collect, analyze, and interpret data using graphs, tables, and statistics. They also learn to understand and apply probability concepts.
  5. Measurement: Students learn to measure and compare quantities such as length, area, volume, weight, and time.

Grade 8 math question papers may include a variety of question types, such as multiple choice, fill-in-the-blank, short answer, and extended response. The questions may test the student’s understanding of math concepts and ability to apply them to solve problems.

Answer

  1. Convert the fraction 3/4 to a decimal:
    • Divide the numerator (3) by the denominator (4) to get the decimal representation: 3/4 = 0.75
    • Result: 0.75
  2. Convert the fraction 5/6 to a percent:
    • Divide the numerator (5) by the denominator (6) and multiply the result by 100% to express it as a percentage: (5/6) x 100% = 83.33333333…%
    • Result: 83.33333333…%
  3. What is the simplified form of the fraction 9/15?
    • Divide the numerator and denominator by their greatest common factor to simplify the fraction: 9/15 = (9/3)/(15/3) = 3/5
    • Result: 3/5
  4. Convert the decimal 0.75 to a fraction:
    • Multiply the decimal by 100 to express it as a fraction with a denominator of 100: 0.75 = 75/100
    • Simplify the fraction by dividing the numerator and denominator by their greatest common factor: 75/100 = (75/25)/(100/25) = 3/4
    • Result: 3/4
  5. Convert the percent 75% to a fraction:
    • Express the percent as a fraction with a denominator of 100: 75% = 75/100
    • Simplify the fraction by dividing the numerator and denominator by their greatest common factor: 75/100 = (75/25)/(100/25) = 3/4
    • Result: 3/4
  6. Simplify the fraction 8/12:
    • Divide the numerator and denominator by their greatest common factor to simplify the fraction: 8/12 = (8/4)/(12/4) = 2/3
    • Result: 2/3
  7. Convert the fraction 2/3 to a decimal:
    • Divide the numerator (2) by the denominator (3) to get the decimal representation: 2/3 = 0.66666666…
    • Result: 0.66666666…
  8. Convert the fraction 7/8 to a percent:
    • Divide the numerator (7) by the denominator (8) and multiply the result by 100% to express it as a percentage: (7/8) x 100% = 87.5%
    • Result: 87.5%
  9. What is the simplified form of the fraction 6/9?
    • Divide the numerator and denominator by their greatest common factor to simplify the fraction: 6/9 = (6/3)/(9/3) = 2/3
    • Result: 2/3
