Dividing fractions are not calculating correctly, I have to manually get the answer I need

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.

just divide 3 by 2 and it gives you 1.5 which is the answer

Try entering on the same command line your calculation followed by the ToFrac command. That should work. Here is a screen capture from a TI83Plus in complex mode (a+ib).

There is no "fraction" button on the TI-83 plus. You will have to press the divide key (2 buttons below the CLEAR key) and then use the parentheses (immediately to the left of the divide key) to tell the calculator the correct order of operations. For example, "1/3x+9" means ".333333x+9", but "1/(3x)+9" means the "x" goes on the bottom of the fraction.

Hello,
To convert from fractions to decimals, and from decimals to fractions use the [S<-->D] key. If you want your decimal results to have a fixed number of decimal places press [SHIFT][SETUP][6:Fix]. Screen shows Fix 0~9. Enter the number of decimal places exemple 3.
Dans ce cas 1/6 is displayes ase 0.167.
Hope it helps.

Hello,
To convert fractions to decimals or decimals to fractions, you use the [S<->D] key. Each time you press the key the result is displayed in the other format.
Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

Hope it helps.

Proper fraction e.g. 3/5, input 3, divide, 5, =, answer 0.6

Improper fraction, either enter as improper fraction, or enter the whole number first, then +, then the proper fraction as before, then =.

E.g. 8/5 which is "1 and 3/5': enter 1, +, 3, "divide", 5 =, answer is 1.6

Or, just 8, "divide", 5, same 1.6 answer. Why go to mixed number first?

13/5 which is "2 and 3/5", enter 2, +, 3, "divide", 5, =, answer is 2.6. Or, just 13/5, same answer

When you get a fraction for he answer: shift-S<->D[a b/c<->d/c]

This way, you change it to a mixed fraction or improper fraction

you can also go press the 'mode' button, and go down until you're at 'Exact/Approx' and choose '3: Approximate'
