Answer:
1/10
Step-by-step explanation:
1/5÷2/1=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
1/5×1/2=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
1×1 /5×2=1/10
This fraction cannot be reduced.
Therefore:
1/5×1/2=1/10
1/2 + 1/3 PLEASEE in fraction
1/12
This is because a common number between the two is 12 so 1/2 + 1/3 = 1/12
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Answer: 76m
Step-by-step explanation:
First, start by splitting the figure into 2 smaller rectangular prisms; this can be done vertically or horizontally. I'll solve both ways so you can understand better.
Method 1: Splitting the figure into 2 rectangles vertically
The formula for volume or a rectangular prism is V = Bh. So, you start by finding the base of rectangular prism 1, which you can solve by multiplying the width (2m) by the length (4m) which is given in the figure. This gives you 8m which is the base. Now, if you look at the figure you can see that the height is 5m, so to find the volume of rectangular prism 1, you would multiply 8m (the base) by 5m (the height), and the answer is 40m.
Next, you would solve the same way to find the volume of rectangular prism 2. The given length is 4m and you can figure out the width by subtracting 5m - 2m which gives you 3m. Now you know your base which is 4m. To solve for the height you must again subtract 5m - 2m to get 3m. To find the volume, plug the values into the formula and multiply 4 X 3 X 3. The volume of rectangular prism 2 should come out to be 36m.
The last step is to add both of these volumes together. The volume of rectangular prism 1 + volume of rectangular prism 2 = Volume of the entire figure. The final volume is 40m + 36m = 76m.
Method 2: Splitting the figure into 2 rectangles horizontally
The formula for volume or a rectangular prism is V = Bh. So, you start by finding the base of rectangular prism 1, which you can solve by multiplying the length (2m) by the width (4m) which is given in the figure. This gives you 8m which is the base. Now, if you look at the figure you can see that the height is 2m, so to find the volume of rectangular prism 1, you would multiply 8m (the base) by 2m (the height), and the answer is 16m.
Next, you would solve the same way to find the volume of rectangular prism 2. The given length is 5m and the given width is 4m. Now you know your base which is 4m. To solve for the height you must subtract 5m - 2m to get 3m. To find the volume, plug the values into the formula and multiply 5 X 4 X 3. The volume of rectangular prism 2 should come out to be 60m.
The last step is to add both of these volumes together. The volume of rectangular prism 1 + volume of rectangular prism 2 = Volume of the entire figure. The final volume is 16m + 60m = 76m.
Hope this helps!

( - ) × ( + ) = ( - )
Accordingly, let us solve it now.
10m + ( – 8 ) + 9m + ( – 10m )
Solve the brackets.
10m - 8 + 9m - 10m

30 lbs of potatoes cost $360. How much would 13 lbs cost?
Answer:
$156
Step-by-step explanation:
To find how many pounds of potatos an amount is, it's valuable to find how much *one* pound is
With just dividing both sides by 30, we can get that one pount of potatos costs $12
Since we want how much 13 pounds we cost, simply multiple 12 by 13 which gives us an amount of $156

- Can a whole number be 5 more than another number and
also 5 times as many as the other number? Give an example
to explain your answer.
Answer:
Nope
Step-by-step explain
1+5=6
6/5 is not 1
2+5=7
7/5 is not 2
NO, a whole number can't be 5 more than another number, & 5 times another number.
Let a whole number be = n
5 more than whole number = n + 5 ; And 5 times the whole number = 5n
Equating them , n + 5 = 5n
5n - n = 5
4n = 5
n = 5 / 4
5 / 4 is not a whole number, as it is in fractional form.
Also, 5/4 + 5 = (5 + 20) / 4 = 25 / 4
5 / 4 x 5 = 25 / 4
Both above sum & product are also in fractional form, so are not whole numbers.
Hence proven.

The population of Missoula, MT was 67,358 people in 2010. What was the increase if there were 75,516 people in 2019? What was the average increase per year?
Answer: 906
Step-by-step explanation:
75,516-67,358= 8,158
2019-2010= 9 years
8,158÷9= 906
The increase in the population is 8158 and average increase in the population per year is 906.4.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given that,
Population of Missoula in 2010 = 67,358
Population of Missoula in 2019 = 75,516
Increase in the population = 75,516 - 67,358 = 8158
Average increase in the population per year = 8158 / (2019 - 2010)
= 8158 / 9
= 906.4
Hence the increase in the population is 8158 and average increase per year is 906.4.
