David and Jillian are playing a board game together. Jillian wants to trade her wool cards for David's ore cards. The double number line shows that 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?

The answer is 8

Step-by-step explanation:

so first we have to figure out how much wool card cost for 1 ore card. 6 divided by 3 is 2. That means for 1 ore card Jillian needs to give David 2 wool cards so if you multiply 4 times 2 you get 8. The 4 is representing the ore cards and since Jillian is trying to get 4 ore cards she has to add 2 , 4 times. 2+2+2+2 gives you 8 (2 x 4)

I hoped that helped

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
