Answer 1

1) (¹¹/₁₈-⁴/₉)* ³/₁₆ = ¹/₃₂
     ¹¹/₁₈-⁴/₉ = ¹¹/₁₈ - ⁸/₁₈ = ¹¹⁻⁸/₁₈ = ³/₁₈ = ¹/₆
     ¹/₆ × ³/₁₆ = ³/₆ₓ₁₆ = ¹/₂ₓ₁₆ = ¹/₃₁

2) ¹¹/₁₈ - ⁴/₉ * ³/₁₆ = ¹¹/₁₈ - ⁴ˣ³/₉ₓ₁₆ = ¹¹/₁₈ - ¹/₁₂ = ²²/₃₆ - ³/₃₆ = ¹⁹/₃₆

3)1³/₅ * (³/₄ + 1³/₁₈) = 3¹/₁₅
³/₄ + 1³/₁₈ = ⁹ˣ³/₃₆ + ²¹/₁₈ = ²⁷/₃₆ + ⁴²/₃₆ = ²⁷⁺⁴²/₃₆ = ⁶⁹/₃₆ = ²³/₁₂
1³/₅ × ²³/₁₂ = ⁸/₅ × ²³/₁₂ = ⁸ˣ²³/₅ₓ₁₂ = ²ˣ²³/₅ₓ₃ = ⁴⁶/₁₅ = 3¹/₁₅


4) 1³/₅ × ³/₄ + 1³/₈ = 2²³/₄₀
    1³/₅ × ³/₄ = ⁸/₅ × ³/₄ = ⁸ˣ³/₅ₓ₄ = ⁶/₅ 
     ⁶/₅ + 1³/₈ = ⁶/₅ + ¹¹/₈= ⁶ˣ⁸/₄₀ + ¹¹ˣ⁵/₄₀= ⁴⁸/₄₀ + ⁵⁵/₄₀ = ⁴⁸⁺⁵⁵/₄₀= ¹⁰³/₄₀ =2²³/₄₀

5) 133⁴/₅ × ³/₄ + 1³/₄ = 133,8 × 0,75 + 1,75 = 100,35 + 1,75 = 102,1

Calculations

1) Calculation 1: - The expression is (11/18 - 4/9) * 3/16. - First, solve the brackets: 11/18 - 4/9 = 1/18. - Then, multiply by 3/16: 1/18 * 3/16 = 1/96.

2) Calculation 2: - The expression is 11/18 - 4/9 * 3/16. - First, solve the multiplication: 4/9 * 3/16 = 1/12. - Then, subtract from 11/18: 11/18 - 1/12 = 11/18 - 2/24 = 11/18 - 1/12 = 5/36.

3) Calculation 3: - The expression is 1 + 3/5 * (3/4 + 1 + 3/18). - First, solve the brackets: 3/4 + 1 + 3/18 = 1 + 3/5. - Then, multiply by 3/5: 1 * 3/5 = 3/5.

4) Calculation 4: - The expression is 1 + 3/5 * 3/4 + 1 + 3/8. - First, solve the multiplication: 3/5 * 3/4 = 9/20. - Then, add to 1 + 3/8: 1 + 9/20 + 3/8 = 1 + 9/20 + 15/40 = 1 + 9/20 + 15/40 = 1 + 9/20 + 3/20 = 1 + 12/20 = 1 + 3/5 = 8/5.

5) Calculation 5: - The expression is 133 4/5 * 3/4 + 1 3/4. - First, convert the mixed number to an improper fraction: 133 4/5 = 669/5. - Then, solve the multiplication: 669/5 * 3/4 = 1003/4.

Results

1) The result of (11/18 - 4/9) * 3/16 is 1/96. 2) The result of 11/18 - 4/9 * 3/16 is 5/36. 3) The result of 1 + 3/5 * (3/4 + 1 + 3/18) is 3/5. 4) The result of 1 + 3/5 * 3/4 + 1 + 3/8 is 8/5. 5) The result of 133 4/5 * 3/4 + 1 3/4 is 1003/4.
