The worksheet contains various subtraction problems involving fractions and mixed numbers. Let's go through the first few problems step by step:

### 1. \( 7 \dfrac{2}{3} - 3 \dfrac{5}{12} \)
- Convert to improper fractions:
  \[
  7 \dfrac{2}{3} = \dfrac{21 + 2}{3} = \dfrac{23}{3}, \quad 3 \dfrac{5}{12} = \dfrac{36 + 5}{12} = \dfrac{41}{12}
  \]
- Find a common denominator (12):
  \[
  \dfrac{23}{3} = \dfrac{92}{12}, \quad \dfrac{41}{12} = \dfrac{41}{12}
  \]
- Subtract:
  \[
  \dfrac{92}{12} - \dfrac{41}{12} = \dfrac{51}{12} = \dfrac{17}{4} = 4 \dfrac{1}{4}
  \]

### 2. \( 3 \dfrac{4}{5} - 1 \dfrac{5}{10} \)
- Convert to improper fractions:
  \[
  3 \dfrac{4}{5} = \dfrac{19}{5}, \quad 1 \dfrac{5}{10} = \dfrac{15}{10} = \dfrac{3}{2}
  \]
- Find a common denominator (10):
  \[
  \dfrac{19}{5} = \dfrac{38}{10}, \quad \dfrac{3}{2} = \dfrac{15}{10}
  \]
- Subtract:
  \[
  \dfrac
