Question

How do you simplify 3/7 - 4/m

Answer 1

Answer: The required simplified form of the given expression is

`(3m-28)/(7m).`

Step-by-step explanation: We are given to explain the simplification of the following repression :

`E=(3)/(7)-(4)/(m)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

Since the denominators are different in both the fractions, so we wiill take the L.C.M. of the denominators.

Now, L.CM.(7, m) = 7m.

So, we have from (i) that

`E\\\\\\=(3)/(7)-(4)/(m)\\\\\\=(3* m-4*7)/(7m)\\\\\\=(3m-28)/(7m).`

Thus, the required simplified form of the given expression is

`(3m-28)/(7m).`

Answer 2

it can not be more simplified
but 3m-28/7m can be an option
