Question

david and jillian are playing a board game together. jillian wants to trade her wool cards for davids ore cards. the double number line shows that david will trade 3 ore cards to jillian for 6 wool cards. ore cards: 0, 3; wool cards: 0, 6. based on the ratio shown in the double number line, how many wool cards does jillian need to trade for 4 ore cards? blank wool cards

Explanation:

Step1: Find the ratio of wool to ore

From the double number line, 3 ore cards correspond to 6 wool cards. So the ratio of wool to ore is $\frac{6}{3} = 2$ wool cards per ore card.

Step2: Calculate wool for 4 ore

To find the number of wool cards for 4 ore cards, multiply the number of ore cards by the ratio. So $4 \times 2 = 8$.

Answer:

8
