Dialogue: 0,0:02:19.67,0:02:24.29,Default,,0000,0000,0000,,But if it says to deliver\Nthe answer as a mixed number
Dialogue: 0,0:02:24.29,0:02:28.29,Default,,0000,0000,0000,,then what you need to do\Nis press alpha y equals
Dialogue: 0,0:02:30.88,0:02:32.24,Default,,0000,0000,0000,,and then right down here
Dialogue: 0,0:02:32.24,0:02:36.41,Default,,0000,0000,0000,,option number three will\Nconvert it to a mixed number
Dialogue: 0,0:02:37.84,0:02:39.80,Default,,0000,0000,0000,,and if it's a mixed\Nnumber it'll convert it

Dialogue: 0,0:02:57.52,0:03:02.04,Default,,0000,0000,0000,,like let's say we want to\Ncube it to the power three

Dialogue: 0,0:03:20.21,0:03:23.42,Default,,0000,0000,0000,,but we can do fractions just the same.
Dialogue: 0,0:03:23.42,0:03:27.09,Default,,0000,0000,0000,,My previous example lets add 3/11
Dialogue: 0,0:03:28.68,0:03:31.11,Default,,0000,0000,0000,,and what I'm doing is I'm\Nputting it in parenthesis

Dialogue: 0,0:03:40.94,0:03:42.50,Default,,0000,0000,0000,,and it gives us the answer
Dialogue: 0,0:03:42.50,0:03:44.68,Default,,0000,0000,0000,,but it gives us in the form of a decimal.
Dialogue: 0,0:03:44.68,0:03:46.77,Default,,0000,0000,0000,,We can convert the decimal into a fraction
Dialogue: 0,0:03:46.77,0:03:50.40,Default,,0000,0000,0000,,by pressing the math key on\Nthe far left of the keypad
Dialogue: 0,0:03:50.40,0:03:54.04,Default,,0000,0000,0000,,and choosing number one\Nconvert to fraction.
Dialogue: 0,0:03:54.04,0:03:57.70,Default,,0000,0000,0000,,And like so and here we are 7/11.
Dialogue: 0,0:04:01.89,0:04:04.42,Default,,0000,0000,0000,,One thing to keep in mind
Dialogue: 0,0:04:04.42,0:04:07.55,Default,,0000,0000,0000,,let's say that we want to\Nhave it convert to a fraction

Dialogue: 0,0:04:09.50,0:04:13.66,Default,,0000,0000,0000,,I'm gonna take the 1/3 to\Nthe power three example
Dialogue: 0,0:04:15.83,0:04:18.09,Default,,0000,0000,0000,,and our answer would be 1/27
Dialogue: 0,0:04:18.09,0:04:19.50,Default,,0000,0000,0000,,but I'm going to press
Dialogue: 0,0:04:19.50,0:04:22.69,Default,,0000,0000,0000,,before I press the enter key\NI'm gonna press the math key
Dialogue: 0,0:04:22.69,0:04:24.67,Default,,0000,0000,0000,,and I'm gonna select convert to fraction
Dialogue: 0,0:04:24.67,0:04:27.44,Default,,0000,0000,0000,,so this is entirely all on one line
