Convert it to an improper fraction and divide the denominator into the numerator.
The answer depends on what you wish to convert into a mixed fraction.
convert it into a mixed number
If you know how to turn a mixed number into a fraction and a fraction into a decimal do that then make it negative.
Convert the mixed number to an improper fraction. Any fraction can be expressed as a decimal by dividing the denominator into the numerator.
87/10 IS a mixed fraction so you do not need to do anything to "convert" to a fractional notation.
Convert it to an improper fraction and divide the denominator into the numerator.
The answer depends on what you wish to convert into a mixed fraction.
Convert the mixed fraction to an improper fraction, multiply by the whole number, convert the answer back to a mixed fraction (if required).
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator.
0.06 is the decimal fraction equivalent to 6/100. As a mixed number then 6.06 = 66/100. As an improper fraction then 6.06 = 606/100.
0.714285 does not convert to a mixed fraction, just a fraction. It is: 142857/200000
Convert the mixed number to an improper fraction and proceed.
Convert the mixed number to a fraction and invert numerator and denominator
because a proper fraction is less than1 and a mixed fraction is greater than 1
If doing it without a calculator, then convert each mixed fraction into a top-heavy equivalent fraction and then multiply as for fractions.
You can either add the fractional parts and, if required, convert the answer to a mixed fraction and then add the integer part to the integer parts of the two original numbers; or change both numbers to top-heavy (or improper) fractions, add them and then convert the answer to a mixed fraction.
