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.

$\frac{5}{10} -\frac{3}{10} =\frac{2}{10}=\frac{1}{5}$

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 $\frac{4}{25} -\frac{1}{5}$, you would multiply the second equation by a number that makes its denominator 25.  5 times 5 is 25, so:

$=\frac{4}{25} -(\frac{1}{5} *\frac{5}{5} )\\=\frac{4}{25} -\frac{5}{25} \\=-\frac{1}{25}$

Answer:

$\frac{1}{5}$

Answer 2

Answer:

1/5

Step-by-step explanation:

5/10 -3/10 = 2/10, which simplifies to 1/5. Because they have common denominators, you just subtract the numerator and the denominator stays the same.  2/10, both the numerator and denominator are divisible by 2, so 2/2 is 1 and 10/2 is 5, giving you 1/5.
