Answer:

<em><u>Equal denominators/common denominators</u></em>

Step-by-step explanation:

You need to have equal denominators. If you do not, then you have to multiply the denominators against each other as well as multiplying the same number to the numerator. If a number is a factor of one of the numbers then multiply the number by its other factor so as to get the same number.

<em><u>Ex. 1</u></em>

<em><u>First one explained:</u></em>

2/3 + 4/5

1/3 * 5/5 = 5/15

2/5 * 3/3 = 6/15

5/15 + 6/15 = 11/15

<em><u></u></em>

<h2><em><u>Common denominator = 15</u></em></h2>

<em><u>Ex. 2</u></em>

<em><u>Second one explained:</u></em>

2/8 + 1/4

2/8 + 1/4*2/2 = 2/8 + 2/8

= 4/8

<h2><em><u>Common Denominator = 8</u></em></h2>

Hope this helped,
