Question

Adam has been asked to post a parcel for a family member. He has been told that the parcel weighs 12 lbs 8 oz. 1lb = 16 oz 1lb = 454 g How much does the parcel weigh to the nearest whole kilogram?

Answer 1

To convert the weight of a 12 lbs 8 oz parcel to kilograms, you first convert the weight to ounces, then to grams, and finally to kilograms. The final conversion results in a weight of approximately 5.67 kg, which is rounded to the nearest whole number as 6 kg.

Step-by-step explanation:

The weight of a parcel can be converted from pounds and ounces to kilograms using a two-step process. First, you need to convert the entire weight into ounces, and then convert that result to grams. Finally, convert grams to kilograms.

To convert 12 lbs 8 oz to ounces, calculate as follows: (12 lbs × 16 oz/lb) + 8 oz. This equals 192 oz + 8 oz = 200 oz.

To convert ounces to grams: 200 oz × 28.35 g/oz gives 5670 g.

To find the weight in kilograms, divide the number of grams by 1000, because 1 kg = 1000 g. So, 5670 g ÷ 1000 g/kg gives 5.67 kg. To the nearest whole kilogram, the package weighs 6 kg.

Answer 2

Weight of parcel to the nearest whole kilogram = 6 kg

Step-by-step explanation:

Weight of parcel = 12 lbs 8 oz

1lb = 16 oz also we have 1lb = 454 g

Weight of parcel = 12 lbs 8 oz = 12 + (8/16) lbs = 12.5 lbs

Weight of parcel in g = 12.5*454 = 5675 g

Weight of parcel = 5675 g = 5.675 kg

Weight of parcel to the nearest whole kilogram = 6 kg
