Answer:

15 bags

Step-by-step explanation:

She can fill 5 bags per each pound (because there are 5 $\frac{1}{5}ths$ 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)

A plane has fees for 420 passengers 15% of the seats are empty how many passengers are on the plane

serious [3.7K]

Answer:

357 passengers

Step-by-step explanation:

$\frac{x}{420}=\frac{85}{100}$ (The $\frac{85}{100}$ is 85% of the 100% people because 15% is missing)

When you cross-simplify you get: $\frac{x}{21}=\frac{85}{5}$ which is $\frac{x}{21}=17$

Finally, multiply 17 by 21 to get x.

Therefore, x=357

Two stores offer differently priced sales for the same paper towels, according to the table below. Which store offers the better

blondinia [14]

Answer:
Store 1 has the better deal.

Explanation:
If you divide the amount the prices by the amount of paper towel roll, you would see store 1 has the better deal.

3.60 divided by 12 = 0.30
3.50 divided by 10 = 0.35

As you can see, store 1 is less expensive than store 2. Therefore, store 1 is the better deal.
