Question

3 1/3 feet are cut off a board that is 12 1/4 feet long.How long is the remaining

Answer 1

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 2

`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.
