SOURCE: fractions appear when I divide; not decimals

press 'yellow key' then press 'enter' to see answers in decimal format instead of fractions

Hello,

Once a fraction is entered it can be submitted to all allowable operations, like any other number. So keep the fractions coming. The calculator will reduce them to their simplest expressions.

Hope it helps.

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.

Hi Anonymous,

You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount, but only multiply or divide, never add or subtract, to get an equivalent fraction.

I've only shown the fraction part of your question as 1 is a whole number.

1/2 = 2/4, or 4/8, or 8/16 or 16/32 or 32/64 & so on.

Going the other way, dividing 2/4 by 2 will give 1/2.

But, only divide when the top and bottom would still be whole numbers, for instance you wouldn't use divide for odd number fractions, for example 1/3 or 3/5 etc.

Trust this helps, best regards Alan

To divide fractions proceed as you usually do with any number. Just make sure to enclose each fraction in parentheses. You may want to remember a simple rule: **To divide a fraction by another, multiply the first one by the reciprocal of the other:**

*(a/b)/(c/d)=(ad/bc)*

### 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

Probably the simplest is to convert both numbers to improper fractions then divide.

Some calculators can work with fractions. With one of those, simply enter the first mixed number, then divide by the other.

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
