How do you divide a fraction
Answers
For example:
The reciprocal basically means to "flip" the fraction so...
3/4 -----> 4/3
(Only flip ONE of the fractions not both of them...you can choose either fraction for flip you'd still get the same answer)
Now instead of a division problem we have a multiplication problem now our problem looks like this:
Now we simply multiply across
As you see above I multiplied across to get a final answer of
And that's how you divide a fraction.

do the reciprocal of 6/8 OR 5/7.
5 8 40 20/21
= and simplify

Answer:
The correct option is B) .
Step-by-step explanation:
Consider the provided inequality:
Now distribute 3 inside the parentheses.
Add 6 on both the side of the inequality:
Now, multiply both the sides by a negative sign and reverse the sign of inequality.
Divide both the sides of the inequality by p.
Now consider the provided options.
By observing the provided option it can be concluded that the correct option is B) .

Answer:
84
Step-by-step explanation:
The key to understanding these problems is having a firm idea about what the variables represent. The variable r, for example, has units of shoppers per minute. This means you will need to divide the number of shoppers by total minutes to calculate variable r.
Example:
“Little’s law can be applied to any part of the store, such as a particular department or the checkout lines. The store owner determines that, during business hours, approximately 84 shoppers per hour make a purchase and each of these shoppers spend an average of 5 minutes in the checkout line. At any time during business hours, about how many shoppers, on average, are waiting in the checkout line to make a purchase at the Good Deals Store?”
Let’s match units to variables:
“…shoppers spend an average of 5 minutes…” This sounds like the description of variable T. We now know that T = 5 in our problem.
“…approximately 84 shoppers per hour…” is close to the units needed for r; however, r is in shoppers per minute, not hour. To fix this, we convert 84 shoppers / 60 minutes = 1.4. We know that r = 1.4.
We want to know, “…about how many shoppers, on average…,” which are the units for N.
This paragraph was a long-winded way of asking you to solve for N! The actual math involved in this problem looks like the following:
N = rt
N = (1.4)(5)
N = 7

Step-by-step explanation:
First we need to find the area of the parallelogram, which can be found by the product of the two dimensions.
If the parallelogram has 6 cm and 10 cm, the area is 6 * 10 = 60 cm2
Then to find how many tiles are needed to fill the area of 720 cm2. we can do a rule of three:
1 tile -> 60 cm2
x tiles -> 720 cm2
x = 720 / 60 = 12 tiles
