EXPLANATION:
To convert a fraction to a mixed number we must follow the following steps:
1.First we divide the numerator by the denominator.
2.The quotient becomes the integer part.
3.The remainder that the division gives, becomes the new numerator, and the quotient becomes the whole part, the denominator if it remains the same.
The exercise is as follows: 21/8
Now since 7/8 is a proper fraction, that is to say that its numerator is less than the denominator, it cannot be converted into a mixed fraction.
