<span>Let's add 1/4 and 1/3.Before we can add these fractions, we'll need to change them so they have the same denominator.<span>To do that, we'll have to find the LCD, or lowest common denominator, of 4 and 3.
I got this from the internet u should ask google first befor puting it into brainliy</span></span>
If you want to simplify, it would be 1/2 because we need a number that (in this case) 5 and 10 both go into. They both go into 5 and so divide 5 by 5, and 10 by 5.
36/9=4 so there are 4 seeds in each packet. If she already has 36 plants, she only need 40 more to get the 76 she wants. 40/4=10 so she needs 10 more seed packets.
