Question

You know that there are 1000 grams in a kilogram. You know that a particular infant

weighs 3400 grams. To determine the weight in kg, the ratio and
proportion method should be set up as follows_____?

Answer 1

To convert an infant's weight from grams to kilograms using the ratio and proportion method, set up the proportion 1000 g / 1 kg = 3400 g / x kg. Cross multiply to find x, which represents the infant's weight in kilograms, arriving at x = 3.4 kg.

Step-by-step explanation:

To determine the weight of an infant in kilograms using the ratio and proportion method, you would set up the following equation:

1 kg = 1000 g

We know the infant weighs 3400 g, so we set up the proportion like this:

1000 g / 1 kg = 3400 g / x kg

Now we cross multiply to solve for x:

1000 g × x kg = 3400 g × 1 kg

Which simplifies to:

x = 3400 g / 1000 g/kg

x = 3.4 kg

This means the infant weighs 3.4 kilograms. It's important to express the units in a small and manageable number for ease of interpretation, unless a specific problem requires a different unit like grams for consistency.
