Tommy writes -414 as a fraction using the same method he knows for positive mixed numbers. his work is shown:

multiply the whole number by the denominator: -4⋅4=-16-4·4=-16.
add the numerator: -16+1=-15-16+1=-15.
write this number over the original denominator: -414=-154-414=-154.

does this method work to correctly write -414 as a fraction?
