It takes 1 gallon of paint to cover 18 fence boards. Assuming you can only buy whole gallons of paint at the store, how many gallons do you need to paint all 150 boards?

9 gal

Step-by-step explanation:

150/18

8.333333333333334

if we round that to the greater whole gallon we get 9 gallons

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 : )
