Start by adding like-terms [⅓ and 2⁄9] with 9 being the Least Common Denominator [LCD]. Since 2⁄9 already has a 9 in the denominator, it does not get touched, so in order to make ⅓ a denominator of 9, we simply multiply both terms by 3, to get 3⁄9. So, adding that to 2⁄9 gives you 5⁄9, also giving you 5⁄9 + x > ⅚. Now, we have to find the LCD again because we have two unlike fractions. Now, our Least Common Denominator is 18, so multiply both terms in ⅚ by 3 [15⁄18] and multiply both terms in 5⁄9 by 2 [10⁄18]. Now you have two like fractions to work with, and you can clearly see that your answer is x > 5⁄18. Although the answer is written in reverse, it is still the same concept.

A farmer needs to fence a rectangular piece of land.She wants the length of the field to be 55 feet longer than the width. If sh

Call the width ' W '.
Then the length is W + 55

Perimeter (distance all around) = W + (W+55) + W + (W+55) = 4W + 110

4W + 110 = 1,310

4W = 1,200

W = 300-ft

Length = W + 55 = 355-ft
