OK
10,538
223
[]
volunteer
right
10,538
224
[]
student
Wait, one divided by 14?
10,538
225
[]
student
0.
10,538
226
[]
student
0714.
10,538
227
[]
volunteer
Yeah
10,538
228
[]
volunteer
You didn't do that on paper though, did you?
10,538
229
[]
volunteer
No.
10,538
230
[]
student
No, I use my calculator.
10,538
231
[]
student
Yeah.
10,538
232
[]
volunteer
But you could. It would take a while.
10,538
233
[]
volunteer
So, so you've got the 0.0714, you multiply that by 100, so you just move the decimal 0.2 to the right.
10,538
234
[]
volunteer
So it's 7.1.
10,538
235
[]
volunteer
7.14%
10,538
236
[]
student
So
10,538
237
[]
student
OK
10,538
238
[]
volunteer
Now, some of them
10,538
239
[]
volunteer
some of them you
10,538
240
[]
volunteer
just can know automatically, like what's 11 half, how many is that?
10,538
241
[]
student
1/2, that's 50%.
10,538
242
[]
volunteer
Right? And what's 1 quarter?
10,538
243
[]
student
25%?
10,538
244
[]
volunteer
and 15th
10,538
245
[]
student
Um, 20%.
10,538
246
[]
volunteer
Good. Um,
10,538
247
[]
volunteer
and of course, 1/10 is 10%.
10,538
248
[]
student
Yeah
10,538
249
[]
volunteer
So you also see then, then, so what's 120th?
10,538
250
[]
student
5%
10,538
251
[]
volunteer
Good
10,538
252
[]
volunteer
Now, that's, so you've got a good set of benchmarks there's for estimating and then you can learn
10,538
253
[]
volunteer
that 16
10,538
254
[]
volunteer
because once 1/6 is 1 is 0.16666, right?
10,538
255
[]
volunteer
Let me write it down. I don't want you to get all confused, but
10,538
256
[]
volunteer
16 equals 0.16666 equals
10,538
257
[]
student
OK
10,538
258
[]
volunteer
16, but I say you can remember 16, but it's closer to 17%.
10,538
259
[]
student
Yeah
10,538
260
[]
volunteer
17 we just figured out is 14%.
10,538
261
[]
volunteer
1 point, what was it? 1.
10,538
262
[]
volunteer
4142
10,538
263
[]
volunteer
But it's roughly
10,538
264
[]
volunteer
but these are just rough estimations.
10,538
265
[]
volunteer
18 is 0.125.
10,538
266
[]
volunteer
And so if you have those, you can kinda quickly do some calculations.
10,538
267
[]
student
Mhm
10,538
268
[]
student
Yeah
10,538
269
[]
volunteer
because 7 and 14 go together, right? 2 x 7 is 14, so you can remember when 7 is 14, and the 6th
10,538
270
[]
volunteer
16th.
10,538
271
[]
student
Mm.
10,538
272
[]
volunteer
That means 16th is also 6%. OK, so those are the percents. If you can divide then the percents aren't hard.
10,538
273
[]
volunteer
Just move that decimal point.
10,538
274
[]
student
OK
10,538
275
[]
student
divide
10,538
276
[]
student
wait
10,538
277
[]
student
What do you want me to do?
10,538
278
[]
volunteer
Oh, no, I was, I was, didn't have a question.
10,538
279
[]
student
Oh.
10,538
280
[]
volunteer
It's your turn. Do you have a question?
10,538
281
[]
student
Uh,
10,538
282
[]
volunteer
Yeah.
10,538
283
[]
student
no. Can you, can we also work on something else, uh, like, like absolute value.
10,538
284
[]
volunteer
OK
10,538
285
[]
volunteer
Let's erase this. and let's, we don't have to erase it, we can go down. I'm gonna scroll down.
10,538
286
[]
volunteer
So
10,538
287
[]
volunteer
an absolute value.
10,538
288
[]
volunteer
is
10,538
289
[]
volunteer
a number without any direction.
10,538
290
[]
student
I
10,538
291
[]
volunteer
The number line
10,538
292
[]
volunteer
on a number line
10,538
293
[]
volunteer
the numbers are either below or above.
10,538
294
[]
volunteer
0, right
10,538
295
[]
student
OK.
10,538
296
[]
volunteer
So we have minus
10,538
297
[]
volunteer
4, -3
10,538
298
[]
volunteer
-2
10,538
299
[]
student
suspension
10,538
300
[]
student
Oh, sorry.
10,538
301
[]
volunteer
1
10,538
302
[]
volunteer
That's OK
10,538
303
[]
student
I
10,538
304
[]
volunteer
1
10,538
305
[]
student
E.
10,538
306
[]
volunteer
OK, so
10,538
307
[]
student
uh.
10,538
308
[]
volunteer
so
10,538
309
[]
volunteer
3
10,538
310
[]
volunteer
is
10,538
311
[]
student
and
10,538
312
[]
volunteer
a distance of 3 in one direction, right?
10,538
313
[]
student
OK
10,538
314
[]
volunteer
And -3
10,538
315
[]
volunteer
is
10,538
316
[]
volunteer
the same distance, but in the opposite direction.
10,538
317
[]
student
Yeah
10,538
318
[]
volunteer
And if you add them up, you get 0. There's 31 way and 3 the other way, you get 0.
10,538
319
[]
volunteer
The absolute value means just how far it is, how great it is without any.
10,538
320
[]
volunteer
infection.
10,538
321
[]
student
I.
