Barry read 1/2 of a book in the morning, and he read some more at night. By the end of the day, he still had 1/3 of the book left to read. How much of the book did Barry read at night?
write it in a fraction

he read about 16/100 of the book at night

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 : )
