What's the common denominator between 210 and 770

Mathematics

Kipish [7]3 years ago

Suppose you want to combine the fractions 13/210 and 29/770.  What's the LCD?

Factor both 210 and 770:  3*7*10 and 7*11*10.  Form the LCD using the common factors 7 and 10 and the unique factors 3 and 11.  The LCD is thus 3(7)(10)(11), or 2310.

Then 13/210 and 29/770 become 143/2310 and 87/2310.  We can add these because their denominators are the same.

So the desired LCD is 2310.

I don’t get how to do it please help????
bonufazy [111]

To put this into simpler terms, well simplier for me anyways, Emma is dividing 9 inches of paper into 2/5, or .4, inches of paper.

That being said, we now just need to divide 9 by 2/5 or .4

We get 22.5

So Emma will be able to make 22 strips since we can't have half a strip. (Well, we could, but it would be small than what we need)

  • Solving systems of equations by graphing

Step-by-step explanation:

If the lines are parallel, they will have no solutions.

If the lines are the same, they will have infinite solutions.

If the lines are anything else, they will usually have 1 solution.

If we graph the systems of equations, we see that the lines are parallel.

∴ the systems has no solution.
