How can you use the reciprocal of a number by a mixed number?

Convert the mixed number into an improper (top-heavy) fraction first. Then swap the numerator and denominator.

What is the definition of dividing fractions and mixed numbers?

The definition is the same as the definition of just about any division. Dividing by a number can be defined as multiplying by the reciprocal of the number. The reciprocal is the number which, when multiplied by a number, results in a product of 1. For example, dividing by 2 is defined as multiplying by 1/2 (since 2 x 1/2 = 1). Division can also be defined as finding a solution of an inverse multiplication problem. For example, 5 / 2 = x is equivalent to x times 2 = 5; thus, the division can be defined as finding a number that solves the multiplication. Although I didn't use mixed fractions in the above examples, the definitions are exactly the same for mixed numbers.

How can you use a reciprocal change a division problem into a multiplication problem?

Division by a number is the same as multiplication by its reciprocal. That is, n / a = n * (1/a) and as you should know, (1/a) is the reciprocal of a.

When do you use a reciprocal?

you can use the reciprocal in this situation: (1/4)^-2 to get rid of the "-" in front of the power, you can just use the reciprocal of the number in brackets: (4/1)^2 which is of course: 4^2 which would equal: 16 You may also use a reciprocal in a situation like this: 1/4 divided by 1/2 you would use the reciprocal of the second number to turn the divide into a multiplication: 1/4 X 2/1 which would equal: 1/2 There r probably a lot of other ways too, but those r possibly the most common hope this helped XD

Why do you use the reciprocal when dividing fractions?

Think of it like this.... If we are dividing fractions and we set those fractions up in a fraction such as, 2/3 ___ 3/4 then how would we get rid of the bottom fraction? We would multiply it by the reciprocal 4/3, so that it's now equal to one, and then because we multiplied the bottom by 4/3, we must also multiply the top by 4/3. So now we have... 2/3 * 4/3 _______ 3/4 * 4/3 = 8/9 ___ 1 = 8/9 That's why we multiply by the reciprocal of a fraction when dividing! E2020 people this should be in your notes? The reciprocal is one of two numbers whose product is 1; it is also called multiplicative inverse.

Why does dividing fractions involve multiplication?

Dividing fractions invole multiplacation because you can use it too see how many time's a number goes into another answer. And that is why dividing involves multiplacation.
