Can you guys plz help If four-fifths of the pizza provided 16 pieces to the table, how many pieces were in the pizza when it was full? Support your answer with a model. Answer in a sentence.

20 pieces

Step-by-step explanation:

x= the entire pizza

if 4/5x=16

divide both sides by 4

1/5x=4

multiply both sides by 5

x=20

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 : )
