1/3 = 0.333333...                    1/6 = 0.16666666...

2/3 = 0.666666...                    5/6 = 0.8333333...

If you get something like                 0.142857142857...

you can use this procedure:

first, set the decimal to n:  n  =   0.142857142857...

then, figure out what you have to multiply by to move the whole group of decimals one cycle the part that's repeated) over; in this case, since the cycle consists of 6 digits, multiply by 10^6 = 1 000 000:

                1 000 000n  = 142857.142857...

                                n  =           0.142857... 

subtract:    999 999n  =  142857

                                n  =  142 857 / 999 999

reduce:                   n   =  1 / 7                (This is a harder example then what you'll probably get.)

Km, kilometers, is a measure of length; this cannot be directed converted to square meters.

1)  To find adjusted gross inome, add what he earned in wages and the amount of interest that he earned.

2)  To find his taxable income , subtract the standard deduction for a single person from his adjusted gross income that you found in step 1.

3)  The amount of tax cannot be calculated from the information given; you will need to look this up in a tax table, or calculate a percentage, depending upon the information that you are given.

4)  The size of the refund is found by subtracting the amount of tax owed from the amount that his employer withheld.

If you draw a point where they started, a point where the one moving north is, and a point where the one moving east is, these three points will form a triangle with a right angle at the point where they started.

You can use the Pythagorean Theorem to calculator their distance apart. One leg is 20, another leg is 15 and the hypotenuse is the unknown distance.

Pythagorean Theorem:  c²  =  a² + b²

where c is the length of the hypotenuse (the unknown) and a and b are the known legs:

 c²  =  a² + b²   --->    c²  =  20² + 15²   --->    c²  =  400 + 225   --->    c²  =  625   --->  c  =  √625  

     --->   c  =  25

Gross pay:  30 x $8.00 = $240.00

Subtract:

-- federal income tax = $22.00

--state income tax = $7.15

--FICA (6.20% of $240.00) = $14.88

--Medicare tax (1.45% of $240.00) = $3.48

Final amount:  $240.00 - $22.00 - $7.15 - $14.8 - $3.48  =  $192.49

$1000.00 is invested.

2% of $1000.00 is deducted:  $20.00 is deducted; leaving $980.00

12.45% increase of $980.00 is $122.01; at the end of the year, the value is: $1102.01.

Next year: 2% ($22.04) is deducted; leaving $1079.97.

12.45% increase ($134.46) is added; at the end of the year, the value is: $1214.43.

Can you take this forward one more year?

Auxiliary verbs are 'helping' verbs; the most common are:  is/am/are, has/have/had, and do/does.

in log form, 2^10 = 1024 is:  log(to the base 2) 1024 = 10

To find a percentage, divide the part (68) by the whole (75) and multiply by 100.

(68/75) x 100  =  the percentage.

In a cirlce, the diameter is all the way across the center of the circle. A radius is only one-half that, starting from the center and going to one side of the circle.

If you know the diameter, to find the radius, divide the diameter by 2.
