Answer :

[tex] \frac{20}{10} [/tex] cannot be changed to a mixed number. 10 could divide both numerator and denominator. And you get 2.
How you turn 20/10 into a mixed number is you see what the denominator can go into the numerator and in this case it would be 10 and so you see how many times 10 can go into 20 without going over and in this case it would be 2 so the answer would be 2.
