Respuesta :

Your final answer would be 2/3.

The LCD would be 12.

You would have to multiply both the top and bottom of 1/4 to get the denominator to 12.

To do this, you multiply it both the numerator and denominator by 3.

This would leave you with 3/12.

The second fraction already has a denominator of 12 so we will just leave it as is.

Then you add.

3/12 + 5/12

This would give you

8/12

Then you simplify it or "reduce it" by dividing both the top and bottom by 4 to get your final answer.

  • 1/4 + 5/12

The lowest common multiple of the denominator ;

Lowest common multiple of 4 and 12 = 12

1/4 + 5/12 = (3 + 5) / 12

1/4 + 5/12 = 8/12
