A delivery truck delivered 17 kg 900 g of supplies in the morning and 12 kg 700 g in the afternoon. How much total supplies did it deliver?

Correct Answer

Given: Morning delivery = 17 kg 900 g Afternoon delivery = 12 kg 700 g

Calculation: Step 1: Morning delivery = 17 kg 900 g = 17,900 g Step 2: Afternoon delivery = 12 kg 700 g = 12,700 g Step 3: Total = 17,900 g + 12,700 g = 30,600 g = 30 kg 600 g

Alternative Method: Add kg: 17 + 12 = 29 kg Add g: 900 + 700 = 1,600 g = 1 kg 600 g Total = 29 kg + 1 kg 600 g = 30 kg 600 g

Answer: ∴ The truck delivered a total of 30 kg 600 g of supplies.

Explanation

The chapter explains addition of weights. Morning delivery = 17 kg 900 g = 17,900 g. Afternoon delivery = 12 kg 700 g = 12,700 g. Total = 17,900 g + 12,700 g = 30,600 g = 30 kg 600 g. Alternatively: Add kg: 17 + 12 = 29 kg. Add g: 900 + 700 = 1,600 g = 1 kg 600 g. Total = 29 kg + 1 kg 600 g = 30 kg 600 g.

Solution Steps

  1. Convert morning delivery to grams: 17 kg 900 g = 17,900 g

  2. Convert afternoon delivery to grams: 12 kg 700 g = 12,700 g

  3. Add the values: 17,900 g + 12,700 g = 30,600 g

  4. Convert back: 30,600 g = 30 kg 600 g
