Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.
Take one of the fractions. Multiply its numerator and denominator by any integer greater than 1. The result will be a fraction with is equivalent to the fraction that you started with but no longer similar to the other fraction.
Example 7/9 - 2/5 1. Make denominators the same (they're the bottom bits) 7/9*5/5 = 35/45 2/5*9/9 = 18/45 2. Now they're the same 35/45 - 18/45 = 17/45
there are fractions in whole steps
I'll make up an example problem; 2 3/5 - 1 1/4. First get your terms into fraction form 2 3/5 = 13/5 and 1 1/4 = 5/4 so our problem becomes 13/5-5/4 next find the least common denominator ( in this case 20 ) 52/20 - 25/20 = 27/20 then simplify 27/20 = 1 7/20
first u find a common denominator

Step I: Find the LCM of the denominators. Step II: Find equivalent fraction such that the new denominators are the LCM. Step III: Carry out the subtraction on these numerators to arrive at the new numerator. Step IV: New denominator = LCM. Step V: Simplify the fraction.

It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.
The subtacting integers is EWAN ko hahahah!!
