Question

David will trade 3 ore cards to Jillian for 6 wool cards. Based on the ratio shown in the double number line, how many wool cards does Jillian need to trade for 4 ore cards?

Answer 1

Given:

3 ore cards can be traded for 6 wool cards.

To Find:

Number of wool cards 4 ore cards can trade for.

This question is about ratio. The change of value in one variable will cause a proportional change in the value of the other variable.

Here we have:

3 ore cards = 6 wool cards

First, we will find out how many wool cards 1 ore card can change for:

3 ore cards = 6 wool cards

1 ore card = 6 ÷ 3

1 ore card = 2 wool cards

Now that we know 1 ore card can change for 2 wool cards, we can find out how many wool cards 4 ore cards can change for:

1 ore card = 2 wool cards

4 ore cards = 2 x 4

4 ore cards = 8 wool cards

Answer: 4 ore cards can trade for 8 wool cards.
