Since we are trying to calculate the number of cubic yards, let's calculate everything in terms of yards.

Converting inches to yards, we have to divide by 36, since there are 36 inches in a yard.

1 ' = 1/36 yard

Converting square feet to square yards, we divide by 9, since there are 9 square feet in a square yard.

3700 square feet = 411 square yards

Calculating cubic yards, we multiply 411 square yards by 1/36 of a yard.

I get 11.42 cubic yards. So you are safe getting 12 cubic yards.

Good luck,

Paul

### How to convert percent to fraction

1% = 1/100

So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.

For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:

56% = 56/100 = 14/25

- Divide the percent by 100 to get decimal number.
- Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
- Calculate the factor (f) for making the decimal number an integer:
*f*= 10*to power d*

Example:

*f*= 10 power 2 = 100

- Multiply and divide the decimal number x by the factor f:
*x***f*/*f*=*y*/*f*

Example:

2.56 * 100 / 100 = 256 / 100

- Find the greatest common divisor (gcd) of the fraction.
Example:

gcd(256,100) = 4

- Reduce the fraction by dividing the numerator and denominator by the gcd value:
Example:

256 / 100 = (256/4) / (100/4) = 64/25

1% = 1/100

So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.

For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:

56% = 56/100 = 14/25

Use the rules for exponents and you will calculate it by hand

(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3

To enter powers of 10 use the short-cut key [EE]

For example to enter 6.02*10^23 type in** 6.02* [EE] 23**. When you use the EE key, the base (10) should not appear.

(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3

To enter powers of 10 use the short-cut key [EE]

For example to enter 6.02*10^23 type in

Sorry but you are using the word EQUATION incorrectly. All you have is two numbers you want to divide one by the other.

Enter the numerator 1EE (-) 14, press the division key / then enter the 5 EE (-) 12. Press the = sign.

Note: to enter the negative sign in the exponents, use the change sign key marked**(-), (+/-) or [+/-] **. Do not use the regular MINUS sign.

When you use the EE key, you must not enter the 10. It is understood because EE is a shortcut for***10^**.

With the TI-84 type in the following: [1] [2] [6] [divide] [9] [=]

This will give you 14.

This will give you 14.

To raise 10 to a power, use 10^x (the 2nd function of the LOG key). To raise e to a power, use e^x (the 2nd function of the LN key). To raise a number to another, use y^x (the key just above the divide key).

There's a key marked "EE" (for Enter Exponent) just above the "7" key. This key is used to enter decimal exponents. To enter 1x10^23, press 1 EE 2 3

For exponents to other bases, use the y^x key just above the divide key.

For exponents to other bases, use the y^x key just above the divide key.

Hello,

What you deplore is perfectly normal.

7/60= 0.1166666667 the last 6 has been rounded to 7 (result is periodic)

36 + 7/60= 36.1166666667

**36.7 -36-7/60=0.8166666667**

tan(36 + 7/60) = 0.7296582051

Compare the tangents of two close numbers

tan(36.7)= 0.7453770282

tan(36.66666667)=0.7444724166

True, the precision of calculator is limited, but the number of digits it can display has a lot more precision that real-life problems really require.

Hope it helps.

I would press 14 and then press the divide button and then press 10. That would give me 1.4 then i would press the multiply button and press 1 and the divide button and press 4, then i would press equal.

That gives me 0.35

That gives me 0.35
