Fractions are used in real life in many different ways, but they are most commonly used in the cooking, construction and science industries.Fractions appear in everyday media to show information to consumers.None of the problems use large numbers, so there is no need for a calculator as long as one knows their standard times tables.The answer is the numerator of the fraction over the product of the denominator of the fraction with the whole number. ![]() The answer will be a fraction, so users should be prepared to use the / button.This exercise is easy to get accuracy badges and speed badges because there is only one type of problem and if one is familiar with the idea of dividing fractions there is only need for one operation. The user is supposed to perform the division and write the correct answer in a provided box. Divide the numbers: This problem provides a division problem with a fraction being divided by a whole number.There is one type of problem in this exercise: This exercise practices dividing a fraction by a whole number. The Dividing unit fractions by whole numbers exercise shows up in the 5th grade (U.S.) Math Mission, Arithmetic essentials Math Mission, Pre-algebra Math Mission and Mathematics I Math Mission. Multiplying by the reciprocal.5th grade (U.S.) Math Mission, Arithmetic essentials Math Mission, Pre-algebra Math Mission, Mathematics I Math Mission Why dividing by something is the same thing as And, hopefully, what we just drew out may help make sense of Two times one is two, and then I could multiply When I multiply fractions I can just multiply the numerators. The way you could compute this, conceptually, you see that this is 2/15, but you could also say well, It once again will be this section right over here. Thinking about this is this is 1/5 of 2/3, which Which is you just swap the numerator and theĭenominator, which is 1/5. And so, 2/3 divided byįive is the same thing as 2/3 times the reciprocal of five, or the reciprocal of 5/1, So, five is the same thingĪs five wholes, or 5/1. Way you will approach it, but it's nice to thinkĪbout it conceptually, when you divide by any number, it's the same thing as You could think about, and over time this is the We have 1/15 right over here, and then 2/15 right over there. ![]() You have three times five, and you could count 'em if you like. How do I know that? Well, I had one, two, three thirds, and then I divided it into one, two, three, four, five sections, so each of these squares Thirds and I divided them into five equal sections, IĮssentially constructed 15ths. This represents of the whole, then we know what 2/3 divided by five is. But, what does just one of them represent? And if we figure out what There, and another one there, and I would have five equal Notice I could draw that, IĬould draw another one here, another one here, another one Alternatively, multiply 2/3 by 1/5, resulting in 2/15 as the final answer. To find the result of 2/3 divided by 5, divide 2/3 into 5 equal parts, each representing 2/15 of the whole. So, what is one of thoseįive equal sections of my original 2/3? Well, this right over here is one of those five equal Dividing fractions by whole numbers can be done visually or using multiplication. So, one, two, three, and thenįour, and five equal sections. But, if I'm doing it, I might as well just divide everything, all the thirds, into five equal sections, ![]() ![]() Well, the way I could do this is I could divide it intoįive equal sections. Each is 1/3, and we have 2/3, so we are really representing all of this stuff right over here. So, this is, that looks pretty good, three equal sections here. To do that, let me represent 2/3, so let's say that what I'm drawing right over here is a whole. We can first do it in a conceptual way, think about it visually. See if we can figure out what 2/3 divided by five is equal to.
