Answer:
1 and 2/3 pounds
Explanation:
If five science textbooks is equal to six and two third pounds then to find the individual weight of each book you need to take the weight divided by amount which would be 6 and 2/3 divided by 5. Simplifying it you could get 20/3 divided by 5 which would be equal to 20/3/5. This would simplify further to 20/15 which would then become 5/3 pounds which is just 1 and 2/3 pounds
