How to divide 1 2/3 by 3

First make 1 2/3 into a mixed fraction and then divide it by 3.
To make 1 2/3 into a mixed fraction, multiply the whole number, in this case, 1, by the denominator (the bottom number) and then add the numerator (the top number). Thus, we get (1*3+2)/3 or 5/3. Now we have to take 5/3 and divide it by 3. I was taught that in this case, dividing by 3 is the same as multiplying by 1/3. 5/3 x 1/3 = 5/9.

If you have access to a calculator you can always check this. On the calculator, do 2 divided by 3 and add 1. Now take that answer and divide by 3. Write down this answer. Now take 5 and divide by 9. Write down this answer. They should be the same.

Good luck.

Make 1 1/2 into a mixed fraction by taking the integer and multiply it by the denominator (the bottom number) and add the numerator (the top number).

3/4 x 3/2 = 9/8

Good luck.

What to numbers can you multiply to get 280 and add to get-18?

When you say "to numbers" I assume you meant "two numbers."

There is no solution.

For the product of two numbers to be 280, either both numbers must be positive or both numbers must be negative. For the sum of two numbers to be -18, one or both numbers must be negative. Taken together, both numbers must be negative.

We can find two numbers that multiply to 280 and add to +18, then simply take the negative of both numbers.

The square root of 280 is about 16.7. The sum of any two numbers that multiply to 280 must be at least twice that, or at least 33.4. Since 33.4 is greater than 18, there is no solution.

If you want to do it the hard way, take any pair of negative numbers that multiply together to 280, add them together, and see how close you come to -18. For example, -1 and -280 add to -281. -2 and -140 add to -142. -4 and -70 add to -74. -5 and -56 add to -61. -7 and -40 add to -47. -8 and -35 add to -43. -10 and -28 add to -38. -14 and -20 add to -34, which is as close as you can come in the integers.

How do I add or subtract numbers in polar form or rectengular form

If one or both numbers are in polar form, convert it/them to rectangular. Once both numbers are in rectangular form, simply add the two components separately: Add the two x components together, and add the two y components together.

If you're asking how to do this on a particular calculator, please specify the make and model.

Mixed numbers

If the result is positive, type in the integer part then add the fraction part either with the help of the fraction key or the division key. (I do not think that the TI82 has a fraction key.
If it is anything like the TI3 there is command under MATH >Frac. It should be pressed after you enter the mixed number to keep the result as a fraction.
If the mixed number is negative you enclose the whole number in parentheses. Press the change sign (-) key to negate the result.

How do you enter mixed numbers ( whole numbers and fractions i.e 3 3/4)?

You cannot, you must enter 3.75. If you can't figure out what the fraction is, you must first compute the fraction (3/4=.75) and then add it to the whole number (3+.75=3.75)

Adding and subtracting lengths of measurements

You can use the units menu (2nd > 3) to place a unit after some number you want to qualify as being an unit, or you can just type them in like 5_ft + 6_in. Note that you need to add on each part if you are doing mixed measurements; there is no _ft_in combination. So just add each manually - in your case you would do (5_ft + 6_in) - (2_ft + 8_in)
