Let's solve each part of the worksheet step by step. The task is to
find what fraction of each figure is *not* colored.
---
(a)
- The rectangle is divided into
4 equal parts.
-
1 part is colored (blue).
- So,
3 parts are not colored.
- Fraction
not colored = $ \frac{3}{4} $
✔ Answer: $ \frac{3}{4} $
---
(b)
- The triangle is divided into
2 equal parts.
-
1 part is colored.
- So,
1 part is not colored.
- Fraction
not colored = $ \frac{1}{2} $
✔ Answer: $ \frac{1}{2} $
---
(c)
- The rectangle is divided into
6 equal parts (2 rows × 3 columns).
-
2 parts are colored (top-left and top-middle).
- So,
4 parts are not colored.
- Fraction
not colored = $ \frac{4}{6} $
- Simplify: $ \frac{4}{6} = \frac{2}{3} $
✔ Answer: $ \frac{2}{3} $
---
(d)
- The circle is divided into
4 equal parts (quarters).
-
2 parts are colored (bottom-left and bottom-right).
- So,
2 parts are not colored.
- Fraction
not colored = $ \frac{2}{4} $
- Simplify: $ \frac{2}{4} = \frac{1}{2} $
✔ Answer: $ \frac{1}{2} $
---
(e)
- The square grid has
5 rows × 4 columns = 20 small squares.
- Count the
colored squares: only
2 are shaded (center column, middle two).
- So,
20 - 2 = 18 squares are not colored.
- Fraction
not colored = $ \frac{18}{20} $
- Simplify: $ \frac{18}{20} = \frac{9}{10} $
✔ Answer: $ \frac{9}{10} $
---
(f)
- The rectangle is divided into
6 equal parts (2 rows × 3 columns).
-
3 parts are colored (bottom row).
- So,
3 parts are not colored.
- Fraction
not colored = $ \frac{3}{6} $
- Simplify: $ \frac{3}{6} = \frac{1}{2} $
✔ Answer: $ \frac{1}{2} $
---
✔ Final Answers:
| Part | Fraction Not Colored |
|------|------------------------|
| (a) | $ \frac{3}{4} $ |
| (b) | $ \frac{1}{2} $ |
| (c) | $ \frac{2}{3} $ |
| (d) | $ \frac{1}{2} $ |
| (e) | $ \frac{9}{10} $ |
| (f) | $ \frac{1}{2} $ |

📝 Explanation Summary:
To find the fraction that is
not colored, follow these steps:
1. Count the total number of equal parts.
2. Count how many parts are
not colored.
3. Write the fraction: $ \frac{\text{not colored}}{\text{total parts}} $.
4. Simplify if possible.
This helps understand fractions as parts of a whole, focusing on the
unshaded portion.
