A paperback books weighs 175 grams. How many kilograms will a box of 80 books weigh?
14000 just times both number
At track practice, Fred runs the 440 meter dash 6 times a day, 5 days a week. How many kilometers does he run in a week?
To find the weight of a box of books, we need to first calculate the total weight of the books and then convert it to kilograms.
Given that a paperback book weighs 175 grams, we can multiply this weight by the number of books (80) to find the total weight in grams.
Total weight in grams = Weight of a single book × Number of books
= 175 grams/book × 80 books
= 14,000 grams
Now, to convert grams to kilograms, we divide the weight in grams by 1000 since there are 1000 grams in a kilogram.
Weight in kilograms = Weight in grams / 1000
= 14,000 grams / 1000
= 14 kilograms
Therefore, a box of 80 paperback books will weigh 14 kilograms.
