42/4 as a whole or mixed number and in simplified form
AlekseyPX

Answer:

10.5

Step-by-step explanation:

42/4 can be reduced by dividing numerator and denominator by 2:  21/2.

This is an improper fraction.  One way to obtain the equivalent mixed number would be to multiply numerator and denominator of 21/2 by 5, obtaining 105/10, which reuces to 10.5.

We could also divide 42 by 4 in the usual way, obtaining 10.5.
