Answer: The parcel weighs 1 kilogram.
Step-by-step explanation:
1. Let's convert 454 grams to ounces:
[tex](454g)(\frac{0.03527oz}{1g})=16.01oz[/tex]
2. Now, you need to add the weights in ounces given in the problem:
[tex]8oz+16oz+16oz=40oz[/tex]
3. You must convert from ounces to kilograms, as following:
[tex](40oz)(\frac{0.02834Kg)}{1oz})=1.13Kg[/tex]
4. To the nearest whole kilogram:
[tex]1.13Kg=1Kg[/tex]
We are given the parcel weighs in lbs and oz = 12 lbs 8 oz.
We need to convert 12 lbs 8 oz into Kilograms.
Also given 1lb = 16 oz and 1 lb = 454 g.
16oz = 1lb.
Therefore, 1 oz = 1/16 lb
8 oz = 8 × 1/16 = 1/2 lb.
12 lbs 8 oz = 12 lbs + 1/2lb
1 lb = 454 grams
12 lbs = 12 × 454 = 5448 grams.
1/2lb = 1/2 × 454 = 227 grams.
Therefore,
12 lbs 8 oz = 12 lbs + 1/2lb = 5448 grams + 227 grams = 5675 grams.
Let us convert it into Kilograms now.
1000 grams = 1 kilogram
5675 grams = 5675 /1000 = 5.675 Kilograms.
We need to round it to the nearest whole kilogram.
