I will solve this worksheet by identifying the fraction of each shape that is shaded and then simplifying it to its simplest form. I'll go through each shape one by one.
First Row (excluding the example)
1. Octagon
- Total parts: 8
- Shaded parts: 3
- Fraction: 3/8
- Simplest form: 3/8 (already simplified, as 3 and 8 have no common factors other than 1)
2. Star
- Total parts: 10
- Shaded parts: 3
- Fraction: 3/10
- Simplest form: 3/10 (already simplified, as 3 and 10 have no common factors other than 1)
3. Pentagon
- Total parts: 10
- Shaded parts: 2
- Fraction: 2/10
- Simplest form: 1/5 (dividing numerator and denominator by 2)
Second Row
4. Rectangle (3x4 grid)
- Total parts: 12
- Shaded parts: 8
- Fraction: 8/12
- Simplest form: 2/3 (dividing numerator and denominator by 4)
5. Parallelogram (4x5 grid)
- Total parts: 20
- Shaded parts: 12
- Fraction: 12/20
- Simplest form: 3/5 (dividing numerator and denominator by 4)
6. Square (4x4 grid)
- Total parts: 16
- Shaded parts: 10
- Fraction: 10/16
- Simplest form: 5/8 (dividing numerator and denominator by 2)
7. Rectangle (5x6 grid)
- Total parts: 30
- Shaded parts: 15
- Fraction: 15/30
- Simplest form: 1/2 (dividing numerator and denominator by 15)
Third Row
8. Rectangle (5x6 grid)
- Total parts: 30
- Shaded parts: 9
- Fraction: 9/30
- Simplest form: 3/10 (dividing numerator and denominator by 3)
9. Rectangle (5x8 grid)
- Total parts: 40
- Shaded parts: 8
- Fraction: 8/40
- Simplest form: 1/5 (dividing numerator and denominator by 8)
10. T-shape (grid)
- Total parts: 25 (5x5 top + 5x1 bottom = 25)
- Shaded parts: 8 (5 in the vertical bar + 3 in the horizontal bar)
- Fraction: 8/25
- Simplest form: 8/25 (already simplified, as 8 and 25 have no common factors other than 1)
11. Parallelogram (5x6 grid)
- Total parts: 30
- Shaded parts: 10
- Fraction: 10/30
- Simplest form: 1/3 (dividing numerator and denominator by 10)
Final Answer
Here are the completed answers for the worksheet:
First Row:
- Octagon: Fraction Shaded = 3/8, Simplest Form = 3/8
- Star: Fraction Shaded = 3/10, Simplest Form = 3/10
- Pentagon: Fraction Shaded = 2/10, Simplest Form = 1/5
Second Row:
- Rectangle (3x4): Fraction Shaded = 8/12, Simplest Form = 2/3
- Parallelogram (4x5): Fraction Shaded = 12/20, Simplest Form = 3/5
- Square (4x4): Fraction Shaded = 10/16, Simplest Form = 5/8
- Rectangle (5x6): Fraction Shaded = 15/30, Simplest Form = 1/2
Third Row:
- Rectangle (5x6): Fraction Shaded = 9/30, Simplest Form = 3/10
- Rectangle (5x8): Fraction Shaded = 8/40, Simplest Form = 1/5
- T-shape: Fraction Shaded = 8/25, Simplest Form = 8/25
- Parallelogram (5x6): Fraction Shaded = 10/30, Simplest Form = 1/3
