One way to do it is to use estimation. If we say 47 is near to 50 and 3381 is near to 3000 or 4000, we can see what magnitude the answer will be, so let’s take 50 and 3000 to start with. We can drop the last zero of each of these so we get 300÷5=60 so we only have tens and ones. Now let’s see what 50 and 4000 would give us: 80. Once again we only have tens and ones. So that tells us if we divide 3381 by 47 the number will consist of some tens and some ones. The tens digit in 3381 is 8, so we know that the first digit of the quotient must be over the 8. The time you spent reading the explanation I’ve given is longer than the time it would take you do this in your head! If you practice doing estimations like this regularly, you will probably make fewer mistakes. It only takes a few seconds once you get used to the method. Good luck!
Answer:
each individual bag of rice weighs 9-pounds.
Step-by-step explanation:
Based on this information we would need to create an equation for the weight of each individual bag of rice. We are told that a 64lb package contains 4 boxes so...
64 lbs. = 4 boxes
Each box contains a 7-pound bag of beans and 1 bag of rice. Since we are told how much the bag of beans weighs we can multiply this by the number of boxes to calculate its total weight from the package...
7 lb. * 4 = 28 lbs.
Now we know that the bags of beans in the package weights 28 pounds. We now subtract this from the total weight of the package to find the total weight of the bags of rice in the package.
64 lbs. - 28 lbs = 38 lbs.
We can see now that the 4 bags of rice in the package weighs a total of 28 pounds. Therefore, we can divide that total by 4 to calculate the weight of each individual bag of rice...
28 lbs. / 4 = 9 lbs.
Finally, we can see that each individual bag of rice weighs 9-pounds.

The better value is Quick Clean. Quick Clean is $0.03 cheaper per roll of paper towel.
To get there -
1. divide your price by your amount to get the unit price for one of the item (in this case paper towels)
2. do the same for your other price.
3. make sure you are keeping things labeled and separate so you know what means what :)
4. compare the two prices and decide which one answers the question you are being asked (again in this case which is a better deal)
Hope that helps!

Answer:
The proportion is true.
Step-by-step explanation:
By using the formula below, you can test the correctness of any proportion.
![\frac{a}{b}=\frac{c}{d}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D%3D%5Cfrac%7Bc%7D%7Bd%7D)
![ad=bc](https://tex.z-dn.net/?f=ad%3Dbc)
By plugging in the given numbers, you can test the proportion.
![\frac{1.3}{4} =\frac{0.975}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1.3%7D%7B4%7D%20%3D%5Cfrac%7B0.975%7D%7B3%7D)
![1.3(3)=4(0.975)](https://tex.z-dn.net/?f=1.3%283%29%3D4%280.975%29)
![3.9=3.9](https://tex.z-dn.net/?f=3.9%3D3.9)
Thus, the proportion is correct.
