This question is incomplete, the complete question is;
Nine pieces of 8-in. × 12-in. duct that is 2 ft in length is needed for a building. What is the total length (in ft) needed?
Answer:
the total length needed is 24 ft
Step-by-step explanation:
Given the data in the question;
the length of one piece of 8-in. × 12-in. duct is 2 ft
Now to find the total length for nine pieces of the duct;
we simple multiply 2 ft by nine
so
Total length = 9 × 2
we convert the mixed fraction to improper fraction
2 = 8/3
so
Total length = 9 × (8/3) ft
Total length = 24 ft
Therefore, the total length needed is 24 ft
Answer:
15 bags
Step-by-step explanation:
She can fill 5 bags per each pound (because there are 5 per pound)
Since there are 3 pounds, and , again, each pound can fill 5 bags, she will need 15 bags.
Another way too look at it is to ask how many 1/5ths are in 3 pounds. To find this answer mathematically:
3 ÷ 1/5 = 15 because when we divide by a fraction, we need to flip it and then multiply (so 3 ÷ 1/5 is actually 3×5)
