Question

What is 5/10 - 3/10 simplify your answer

Answer 1

The denominators of the fractions are the same, therefore you can just subtract the numerators and you're done.

`(5)/(10) -(3)/(10) =(2)/(10)=(1)/(5)`

If you had different denominators, you would have to multiply one or both of the equation by a common factor to get the denominators to be the same.

For example, if you have
`(4)/(25) -(1)/(5)`, you would multiply the second equation by a number that makes its denominator 25. 5 times 5 is 25, so:

`=(4)/(25) -((1)/(5) *(5)/(5) )\\=(4)/(25) -(5)/(25) \\=-(1)/(25)`

Answer:

`(1)/(5)`
