Question

Circle the expression that is equivalent to x/5+x/10

3x/10 2x/15 x/25 x^2/50

Answer 1

A. 3x/10

Explanation:

`(x)/(5)+(x)/(10)`

Find a common denominator. The lowest common denominator is 10, so match the equations to fit that denominator.

`((x*2)/(5*2))+(x)/(10)\\(2x)/(10)+(x)/(10)`

Now that the denominators are the same, combine the fractions by adding the numerators.

`(3x)/(10)`

Your answer is a.
