Answer:

Explanation:

See,

3 1 12 1

3 4

you would have to multiply both bottoms to 12, then you would get 12 1/12 and 3 1/12 so when subtracting the top would go to zero which would make everything 0 so then it would just be a whole number subtraction problem and 12-3=9

Answer:


8(11)/(12)

Explanation:

In order to answer this question you will have to subtract 3 1/3 from 12 1/4 by turning the mixed fractions into improper fractions, finding the common denominator, (CD) then subtracting the numerators.


12 (1)/(4) - 3(1)/(3)

Turn the mixed fractions into improper fractions:


12(1)/(4) = (49)/(4)


3(1)/(3) = (10)/(3)


(49)/(4) -(10)/(3)

Find the common denominator:


4*3=12


3*4=12


CD=12


49 * 3 =147


=(147)/(12)


10*4=40


=(40)/(4)

Now subtract the numerators:


147-40=107


=(107)/(12)

Turn the improper fraction into a mixed fraction:


(107)/(12) =8(11)/(12)


=8(11)/(12)

Hope this helps.
