student | 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. | 10,538 | 322 | [] |
