Sure, you can write it that way. But for the final result, you should always convert it to a mixed number in standard form, or to an improper fraction.

how can you divide a mixed number

NO

Yes

The answer depends on what you mean by a mixed number. A mixed fraction, for example, is always a rational number - without exception.

8.0843

You have to divide the top and the bottom numbers in the fraction ( numerator, denominator ), and you will always get a mixed number, or a mixed number in lowest terms.

There is no lowest mixed number since, given any mixed number, it is always possible to find a lower one.

what is 2+@

No.The mixed number 21/2, for example, is greater than the whole number 2, but smaller than the whole number 3.In fact, given any mixed number (which does have a fractional part), it is always possible to find a pair of consecutive whole numbers such that the mixed number is between them.

When 1.26 is written as a fraction, the result is 63/50. Written as a mixed fraction, the result is 1 13/50.

Divide the numerator (top number = 50) by the denominator (bottom number = 7) to get a result and remainder; the result is the whole number (of the mixed number) and put the remainder as the numerator over the denominator (to get the fraction of the mixed number):50 ÷ 7 = 7 r 1⇒ 50/7 = 71/7

0.1782

No. 13/4 plus 61/4 = 8

You get a mixed number in which the fraction is always 1/2 .

8 and 7/83

TRUE. A proper fraction is always less than 1 and a mixed number is always greater than 1

It is not clear why a dividend which is a fraction should result in a mixed number of any kind. In any case, being hopeful will not help you to get an answer.

no. lets use 10,000,000,000,000, which is a whole number, and 1 1/2, which is a mixed number. all a mixed number is is a mix of fractions and whole numbers,

The product of two mixed numbers is always greater than one (assuming that both of the mixed numbers themselves are greater than one.)

because a mixed number is a number inbetween two whole numbers, such as 1 1/2 is also 1.5 or 3/2

A mixed number

Not really...simplified it becomes: 90/2 = 45x2/2 = 45 Which is a whole number with no fraction, and hence not strictly "mixed". However if a question asks for a result to be "simplified to a mixed number" then it is saying do not leave any improper fraction as such but convert them to a mixed number or just a whole number if there is no fractional bit (as in this case).

No. The divisor may be an integral multiple of the dividend. For example, 3 1/2 divided by 1 3/4 equals 2. (7/2 divided by 7/4)

A mixed numberThis is called a mixed number or mixed fraction.
