in order to do this question you need to know how many minutes there are in an hour, how many hours in a day how many days in a month and how many months in a year. I would first start out by converting the minutes into hours by the conversion.

there is 60 minutes in every hour so 

6937920/60=115632 This means you have 115,632 hours 

 Now lets convert this into days.

There is 24 hours in every day.

115,632/24=4,818 this means that 6937920 minutes is equivalent to 4818 days.

Now lets convert it into months. we know there is 365 days in a year and 12 months in this said year. We can take the 365/12 giving us an answer of 30.42 with rounding. This number tells us how many days are in an average month.

Now the conversion 4818 days divided by 30.42 days in every month is equal to 158.3826. This means 6937920 minutes is equivalent to 158.38 months.

Convert that into years by dividing 158.38 by 12 considering there is 12 months in every year. This is equal to 13.19855358 which if rounded is roughly 13.2 years.

Overall:

6937920 minutes

115,632 hours

4818 days

158.38 months

13.2 years

you could mean 2 things here. are you trying to convert this into a percent or are you multiplying this by a percent. They are different answers.

(50/300)x100%=1/6

or

(50/300)x100=16.66666666667% or 16.7%

4/3 

An easy way to think about this is  by breaking 1.33 into 2 parts.

First start by taking away the whole number.

Now find the corresponding decimal to fraction. I know 0.33=1/3

Next take 1/3 and add the second factor you had which was the whole number.
1/3+1=4/3. I know this because 3/3=1 so 3/3+1/3=4/3

0.333333=1/3 so if i take 1/3+1=4/3.

If you mean -2^2=4 this is also the same as writing -2*-2=4

This is because if you multiply a negative by a negative you get a positive. As well as 2*2=4

Any number to an even amount of exponents(power) it is always positive

Any negative number to an odd amount of exponents(power) it is always negative

Guest has the proper answer

The answer is N=0.99747959

There is several ways to do this. But one easy way would be to solve the left side first.

For example:

5/6=0.83333333333333333333...

that means X^72=0.83333333...

Now we have a base from which to start.

An easy way is to do the 72nd root of the function. On your calculator you should see something that looks like 

This. --->\(\sqrt[x]{}\)

you should type 72 then press that button and enter 0.8333333333333... and you will find the answer to N. Another way you can do that is in grade 12 Advanced functions in Canada... But im sorry at the moment i dont remember as to how.

This way displayed above should easily get you the right answer.
 

My exact button presses on my calculator is 5 ab/c 6 = ab/c until decimals are shown.  Then i delete the answer so i can type the next function in.Then I do 72\(\sqrt[x]{}\)Ans which means \(\sqrt[72]{0.833333333333}\) Then you should find your answer.

0/4 Does not equal 32 

 If it matters 128/4=32

0 divided by anything equals 0. This is because you cannot break 0 into groups. You should think of division in terms of breaking things into evenly distributed goods. since you are trying to break 0 into 4 groups. Since 0 has no value all groups would be even at 0. 0+0+0+0=0

x(x-8)=(x^2-8x)

*NOTE* Sorry for the messy writing above... I learned how hard it was to write in paint.***

You can solve this by breaking it up into different sections. first make sure you distribute the 8 along all of the possible combinations.

For example:

(x*x) (x*-8)

now we know that x*x= x^2 due to X^2 literally meaning X*X. We also know that X*8=8X but since the 8 is a negative the negative should carry over. so the section should equal -8X. now combine all the sections back together and you should get your answer of (X^2-8X).

Now keep in mind if the question was (x-3)(x+5) you would break it into (X*X)(X*5)(-3*X)(-3*5) You should solve each section. (X^2)(5X)(-3X)(-15) Now combine all of the sections together.  X^2+5X-3X-15. Now simplify the answer X^2+2x-15.

*NOTE* Make sure that all of the combinations are satisfied.

$22.33 

You can get this by collecting easier additions.

For example you start with this

$0.84 + $1.50+ $10.99+ $3.00+ $1.00+ $5.00=

Reorganize it to make the edition easier. (Collect the whole numbers together.)

($3.00+ $1.00+ $5.00)+1.50+10.99+$0.84

This makes it easier to start. 

Add all the whole numbers first

3+1+5=9

Now move onto the decimal answers. An easy way to think of this is by taking .01 away from 1.5 or 0.84 and adding it to the 10.99 to make 11. This makes another whole number which you can add to the total,

9+11=20

Now all you have left is either 1.49+0.84 or 1.50+0.83

Now solve one of the 2 equations.  I would personally fo to the 

1.50+0.83 because 1.5 is the easiest to work with. 

you can subtract 0.50 from 0.83 to make 1.5 a whole number.

0.83-0.50=0.33

1.5+0.5=2

that means you found another whole number due to the 0.5 being added onto the 1.5.

add the whole numbers together 20+2=22.

Now all you have left is the whole number and the small decimal. just attach the small decimal to the whole number such as 22.33

the Answer should be 0. This is due to b.e.d.m.a.s. First you start by solving inside of the brackets first. so 5^2=25.

9-8-7-6-5+3(4)+2(25)/10

Next you have to solve all of the multiplication starting from the left. 

9-8-7-6-5+(12)+2(25)/10

Then the next multiplication

9-8-7-6-5+(12)+(50)/10

Now according to bedmas division is before addition and subtraction so you solve the division.

50/10=5

9-8-7-6-5+12+5

Then solve the rest by adding and subtracting

9-8-7-6-5+12+5=0

*NOTE* keep in mind you solve for whatever comes first... Division or multiplication. In this case All of the multiplication came first so you divided last. If the equation was
