Answer 1

Hi @Ms-Brains

Answer 2

What is the LCD of 3/5 and 7/10?

Answer 3

Couldn't you do midpoint formula that's what I did and I think I got the right answer

Answer 4

Using the midpoint formula would work, but would still require identification and use of the LCD. So, again, M-B, what is the LCD?

Answer 5

I got no clue...
LCD would be what exactly...?

Answer 6

LCD=Lowest Common Denominator. I'm sure you've worked with this concept before.
What is the smallest number you can think of into which you could divide both 5 and 10, separately?

Answer 7

Lowest food on denominator

Answer 8

Lol

Answer 9

Common

Answer 10

Or you could change these to decimals but weather way works

Answer 11

M-B: Please think back to past experience. How have you found the LCD before?

The LCD of 2/3 and 1/6 is 6. How would one know that?

Answer 12

the LCD of 1/2 and 1/6 is also 6. How?

Answer 13

It is very, very disappointing to find that you (@Ms-Brains) have simply logged off in the midst of efforts to help you with this problem.

Answer 14

I'm having trouble staying on, OS keeps getting more and more laggy. I'm super sorry @mathmale I wouldn't do it on purpose, honest. I got sucky internet too, Okay, I worked it out on a piece of paper, and what I got was D has the correct answer by doing this; Average the numbers:

avg = (3/5 + 7/10)/2
avg = (6/10 + 7/10)/2
avg = (13/10)/2
avg = 13/20

Answer 15

Good job at @Ms-Brains :)

Answer 16

:( I still feel bad that MathMale thinks I logged off on purpose. I really appreciate his help! but OS keeps kicking me off.

Answer 17

It's okay @Ms-Brains it's not your fault

Answer 18

Any more questions?

Answer 19

Apology accepted; sorry I didn't think that perhaps it was your Internet connection that was at fault. 13/20 is indeed correct. So glad you were able to arrive at that on your own.

Answer 20

Thank you two for the help! ^u^
