Write 6 1 3 as another mixed number and improper fraction?

Answer 1

Assuming that the number is supposed to be

6 1/3 (six and one third)

We call that a mixed number because it has a whole number (6) plus a fraction (1/3).

To make 6 1/3 into an improper fraction, multiply the denominator (3) by the whole number (6) and add the result to the numerator (1). That gives us 19/3 (nineteen thirds). This is called an "improper" fraction because it is more than one; that is, the numerator is larger than the denominator.

Sometimes it is useful to change a mixed number into a mixed number with an improper fraction. This is usually seen when adding and subtracting mixed numbers. To do this, subtract 1 from the whole number part and add the denominator to the numerator. 6 1/3 = 5 + 3/3 + 1/3 = 5 4/3.

Here is an example of when that can be useful:

Subtract 5 3/4 from 7 1/4

Since we can't really subtract 3/4 from 1/4, we have to borrow (regroup).

Turn the 7 1/4 into 6 5/4

Now subtract 6 5/4 - 5 3/4 = 1 2/4 or 1 1/2.
