Question

Jina is ordering 4 bags of cat food from Canada. Each bag has a mass of 2.5 kg. To determine the shipping costs, Jina needs to know the total weight in pounds. What is the weight of the cat food in pounds? USE 1kg=2.2lb AND DON'T ROUND ANY COMPUTATIONS.

Answer 1

22 pounds

Explanation:

Jina is ordering 4 bags, each of them weighs 2.5 kgs. Let's first find each bag's weight in lbs:

`2.5kg*2.2lb = 5.5 lbs`

Now, to find the total mass of cat food, let's multiply each bag's weight to the number of bags:

`5.5lbs * 4 = 22 lbs`

Answer 2

22 lb

Step-by-step explanation

Given that 1 bag weighs 2.5 kg, then 4 bags will weigh:

`4*2.5\text{ kg}=10\text{ kg}`

Using the conversion factor: 1 kg = 2.2 lb, 10 kg are equivalent to:

`10\text{ kg}=10\text{ kg}*\frac{2.2\text{ lb}}{1\text{ kg}}=22\text{ lb}`
