Chris F (Tutor)

[00:00:12] Hello! I would be glad to help you

Guest (Customer)

[00:00:28] ok

Chris F (Tutor)

[00:00:47] Great, so what problem do you want to work on?

Guest (Customer)

[00:01:04] fractions

Chris F (Tutor)

[00:01:40] Sure. Do you have a specific problem you want to work on with fractions?

Guest (Customer)

[00:02:26] adding and subtracting fractions

Chris F (Tutor)

[00:02:40] Sounds good. Do you want me to come up with a problem?

Guest (Customer)

[00:02:47] ok

Chris F (Tutor)

[00:03:12] We can do 1/2 + 1/4 to start

Guest (Customer)

[00:03:20] ok

Chris F (Tutor)

[00:03:28] Great, so any idea how to start this?

Guest (Customer)

[00:03:51] add the 1`s to gether

Chris F (Tutor)

[00:04:07] We can't add yet because the denominators are different

[00:04:17] We need to find the least common denominator (LCD)

[00:05:29] Any idea how we can find the LCD for 1/2 and 1/4?

Guest (Customer)

[00:05:38] no

[00:06:03] I have a sertant problem

Chris F (Tutor)

[00:06:10] We want to list some multiples of 2 and some multiples of 4. Then we find the lowest one they have in common

[00:07:13] Do you know what some multiples of 2 would be?

Guest (Customer)

[00:07:24] 2and1

Chris F (Tutor)

[00:07:46] Those are factors. For multiples, we start with the number (here, 2), then keep adding that number to itself

Guest (Customer)

[00:08:18] no you don`t

Chris F (Tutor)

[00:08:44] Yes, that is one way to find multiples. You can also multiply 2 times 1, 2 times 2, 2 times 3, etc.

Guest (Customer)

[00:09:48] you suck I'm getting a nother tutor
