Li Na is going to plant 636363 tomato plants and 818181 rhubarb plants.
Li Na would like to plant the plants in rows where each row has the same number of tomato plants and each row has the same number of rhubarb plants.
What is the greatest number of rows Li Na can plant?

Step-by-step explanation:

A method that you can use to find LCM is by just looking at the multiples of these numbers of the numbers an figure out which is the first similar one. You would say, well, let's see. The multiples of 18 are 18, 36, and I could keep going higher and higher, 54.And I could keep going. And the multiples of 12 are 12, 24, 36.And immediately I say, well, I don't have to go any further. I already found a multiple of both, and this is the smallest multiple of both. It is 36

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
