Question 2 of 41intermediate🔧 ApplyNumerical2 marks

The lengths of the body parts of a honeybee are given. Find its total length. Head: 2 3/10 units, Thorax: 5 4/10 units, Abdomen: 7 5/10 units

Correct Answer

Given: Head: 2 3/10 units, Thorax: 5 4/10 units, Abdomen: 7 5/10 units

Formula: Total length = Head + Thorax + Abdomen

Substitution: Total length = 2 3/10 + 5 4/10 + 7 5/10

Calculation: Step 1: Add whole number parts: 2 + 5 + 7 = 14 units Step 2: Add fractional parts: 3/10 + 4/10 + 5/10 = 12/10 = 1 2/10 units Step 3: Combine: 14 + 1 2/10 = 15 2/10 units

Answer: ∴ The total length of the honeybee is 15 2/10 units or 15.2 units.

Explanation

To find the total length, add all three body parts: 2 3/10 + 5 4/10 + 7 5/10. Add the whole numbers: 2 + 5 + 7 = 14. Add the fractional parts: 3/10 + 4/10 + 5/10 = 12/10 = 1 2/10. Total = 14 + 1 2/10 = 15 2/10 units.

Solution Steps

  1. Step 1: Add whole number parts: 2 + 5 + 7 = 14 units

  2. Step 2: Add fractional parts: 3/10 + 4/10 + 5/10 = 12/10 = 1 2/10 units

  3. Step 3: Combine: 14 + 1 2/10 = 15 2/10 units
