- Fractions are just decimals right?(13 votes)
- Fractions are statements where there is a number on top of a number, or a numerator on a denominator.
Decimals are non-whole numbers with a "." or decimal to indicate the moving of the number digits of the number into numbers with values smaller than one.
But fractions can become decimals if you convert them to one.
You divide the top number by the bottom in the fraction to convert it into a decimal.(11 votes)
- whats a denominator?(1 vote)
- When you have a fraction like 3/4, the denominator is the bottom number in the fraction (the 4). The numerator is the top number in the fraction (the 3).(5 votes)
- What would the answer in decimal be? Would it be 0.3?(1 vote)
- why do we use fraction in real life?(1 vote)
- Fractions are used in real life in many different ways, but they are most commonly used in the cooking, construction and science industries. Because fractions describe an object or substance that has been divided into different equal parts, fractions can be found almost anywhere.(1 vote)
- At0:43what does Lindsay mean by sections?(0 votes)
- Some plates have sections, like a cafeteria tray, for different foods. In this example, the plate having sections allow it to be divided into three perfectly equal areas, which is helpful as a fractions example. Each section is one third (1/3) of the plate, so when one is full of broccoli, 1/3 of the plate has broccoli. I hope this helps!(3 votes)
- [Voiceover] This question says, Vera's dinner plate is divided into three equal-sized sections. Vera puts all her broccoli in one section. And then we're asked, what fraction of Vera's plate has broccoli? Okay. So we have we plate with three equal-sized sections, and we know that Vera puts broccoli in one section, and we're asked to figure out what fraction of the plate that is. So we can draw Vera's plate, try to represent this with a picture. Maybe Vera's plate is a rectangle. We don't really know, but a rectangle will work as long as it has three equal-sized sections. So let's try to draw that. This may not be perfect. We can probably do that second one a little better, but this should represent three equal-sized sections on a plate. And then we know she puts broccoli in one of those sections, so let's use green, draw some broccoli. Broccoli, broccoli, broccoli. And then, look at this picture, and ask ourselves, what fraction of Vera's plate has broccoli? Well, our fraction's gonna have a numerator. On top will be how many sections have broccoli, which is one, and then, our denominator will be out of the total number of equal sections, and we know there are three equal-sized sections. So 1/3 or one of the three sections has broccoli.
