The mid-chapter checks with the decimals, the percents, and the fractions
Hey, 6th graders. This is the mid chapter check with the decimals, the percents and the fractions. Hey, it's really important that you understand these things and you read all the directions because percent decimals and fractions. We need to know how to write those all in all of them in simplest form. So pay real attention. I'm going to over explain some of these problems to make sure you did all parts of it right. If we're going to define a percent, that's a part of a hundred. Just like the rap video. So a part of a hundred. So 25 out of a hundred is 25%. 25 out of a hundred, I would just say this 2500 is .25. If you missed the top two, we might be in trouble. That's why we're doing this mid chapter check. Are you red light, yellow light, green light on this stuff? Okay.
So read the directions. Number two, fractions going as a decimal. And then we take each decimal and turn it into a fraction. So we're not even doing percent on two, three, and four. 8 out of 20. Okay? If I was gonna do that as a decimal, which is what it's asking me to do, it's easiest if I can get it out of a hundred. 20 times 5 to get to a hundred, 8 times 5 gives me 40. So 40 out of a hundred is .4. Okay. If I wanted to do that one different way, I could turn that into four out of ten. Just divide it by two. And that's pretty easy to realize. That's also .4. So you can take that fraction, you can go down, take that fraction, and you go up, but the decimal is the same. 64 is just 64 out of a hundred and some of you guys probably just wrote that down, but you're not in simplest form, which is what the directions say. So let's go ahead and divide this by two, which is 32 out of 50.
Let's go ahead and divide that by two, which is 16 out of 25. There I'm done. Okay? And three of them taking a decimal out of this fraction, I would just say three one hundredths. It's important you put point zero three. Okay, some of you guys put .3 and that's definitely wrong. Moving on. We're going to take the percent and we're going to turn them into decimals and the decimals as percent. If I've got 73%, that's the same as 73 out of a hundred, and I can't make those any smaller. I'm done right there. If I've got one tenth, that's the same as one out of ten. Okay, but I'm supposed to turn it into a percent. One out of ten is 10%. This is something we need to have memorized. We've been practicing that one. Have I got 254? Some people realize I just put it out of a hundred. Anytime I take a percent and go to a fraction, I just put a hundred underneath it. But if I've got 254, that's the same as having two with 54 and a hundred left over. That's an even number. That's an even number.
So I've got two and 27 out of 50. There I'm done. Okay? You know what? I made a mistake though. Because I'm supposed to write mister brooker didn't read the directions. That's a .73. You just go scoot scoot, okay? This one, you just go scoot scoot and that's 10%. And then this one you just go scoot scoot and you're gonna get 2.54. I'm sorry I didn't read the directions there. Okay. So you need to know which way I'm moving the decimal place for decimals and percents. Number 8, the number of chorus students increased by a factor of 1.2. 1.2 increase from going from a decimal to a percent. I'm going to the right. Scoot scoot. There we are. 120 percent. Okay? What fraction of the pies was Apple? 42. I know that out of percent, 42% is 42 out of a hundred. But I'm not done there. Okay, because I can divide these by two, so it's 21 out of 50. What percent of strawberry pies is a decimal.
So 12%, I just go. Scoot scoot. So 12% is a decimal is 12 hundredths. And that's pretty easy because we would just put that out of a hundred anyway. And lastly, number ten. Each circle is divided into sections of equal size. Each circle has 20, which one has 25% shaded. So if there were 8 pi pieces, what's 25% of 8? 25 over a hundred is the same as what over 8. Now I know that's one fourth. 25% is one fourth, which is why we got to have these decimals and percent. Figure it out. So what's one fourth of 8? Well, that's two. Okay, so it's not that one, not that one, not that one. It's a and if this was flipped, rotated a little bit, you would see, that two of those are colored. All right. Good job, guys. Let us know if we're red light, green light, or yellow light, and now you should be on Bowie max.
