Guest (Customer)
[00:01:01] Ok thanks
[00:01:44] Do this look right so far

Erin F (Tutor)
[00:02:15] yes, it does, great job! you converted your mixed numbers to improper fractions :)
[00:03:01] ok, do you know what you should do next?

Guest (Customer)
[00:03:41] 11/12

Erin F (Tutor)
[00:04:28] you are almost correct ... you did a great job converting the fractions to have a common denominator ...

Guest (Customer)
[00:04:31] I worked it out on WB And got 11/12

Erin F (Tutor)
[00:05:04] well, both fractions are negative ... do you want to give the addition another try?

Guest (Customer)
[00:05:30] -38/12

Erin F (Tutor)
[00:06:36] that's not quite it ... let's take a look at it together

Guest (Customer)
[00:06:44] Ok

Erin F (Tutor)
[00:07:39] the denominators are the same, so we just need to add the numbers in the numerators
[00:07:49] actually, you had the problem correct all the way to this ...
[00:08:41] do you understand everything up to this point? you had done all those steps correctly :)

Guest (Customer)
[00:08:51] Yes

Erin F (Tutor)
[00:09:01] ok, great!
[00:09:18] so for the next step, we just have to add the numbers in the numerator ...
[00:09:25] which means we add -27 + -16

Guest (Customer)
[00:10:15] -43

Erin F (Tutor)
[00:10:27] ok, yes, that's it now, great job!
[00:10:33] so what does the final fraction look like?

Guest (Customer)
[00:11:22] -43/12

Erin F (Tutor)
[00:11:59] Now, did your teacher say what form the answer should be in (like mixed number or improper fraction) ?

Guest (Customer)
[00:12:13] No

Erin F (Tutor)
[00:12:46] Ok, well since the problem originally started with two mixed numbers, that is the way we should answer it, with a mixed number
[00:13:06] Do you know what we need to do to go from improper fraction to mixed number?

Guest (Customer)
[00:13:18] -3 5/8

Erin F (Tutor)
[00:13:52] ok, the -3 is correct ...

Guest (Customer)
[00:14:33] -3 7/12

Erin F (Tutor)
[00:14:39] yes, that's it, nice work!

Guest (Customer)
[00:14:51] Thanks

Erin F (Tutor)
[00:14:59] Do you have any final questions about what we have done together?
