Answer:
The weight of the trash is 40,900 kilograms
Explanation:
∵ 1 kilogram = 2.2 Ib
That means if you want to convert quantity from Ib to kilogram divide the quantity by 2.2 or you can use the ratio method to do that
→ kg : Ib
→ 1 : 2.2
→ x : 90,000
Now by using cross multiplication
∵ x × 2.2 = 1 × 90,000
∴ 2.2 x = 90,000
- Divide both sides by 2.2
∴ x = 90,000 ÷ 2.2
∴ x = 40909.09091
- Round it to the nearest hundred
∵ The number before the hundred place is 0
∴ The number in the hundred digit will not change
- Change the unit digit and ten digit to 0
∴ x ≅ 40900 to the nearest hundred
∵ x represents the quantity of the trash in kilogram
∴ The weight of the trash is 40900 kilograms
