A small box of nails was 5 2/5 inches tall. If the large box of nails is 7 3/5 inches taller how tall is the large box of nails. Answer as a mixed number.

the height of the large box is 13 in

Step-by-step explanation:

For mixed numbers, the integers are summed with other integers and the fractions are summed with the other fractions, therefore the height of the large box is then

H large = 5 2/5 + 7 3/5 = (5+7) (2/5+3/5) = 12 5/5 = 13 in

thus the height of the large box is 13 in
