Answer:
The combined weight is 13 31/40.
Step-by-step explanation:
Given:
Adam buys a box of stuff that weighed 6 3/8. if he buys box of fruit that weighed 7 2/5.
Now, to find the combined weight.
So, we change the mixed fraction to improper first:
Weight of box of stuff = [tex]6\frac{3}{8}=\frac{51}{8}[/tex].
Weight of box of fruit = [tex]7\frac{2}{5}=\frac{37}{5}[/tex].
Then, by adding to get the combined weight:
[tex]\frac{51}{8}+\frac{37}{5}[/tex]
[tex]=\frac{51\times 5+37\times 8}{40}[/tex]
[tex]=\frac{255+296}{40}[/tex]
[tex]=\frac{551}{40}[/tex]
[tex]=13\frac{31}{40}[/tex]
Therefore, the combined weight is 13 31/40.
