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 =
.
Weight of box of fruit =
.
Then, by adding to get the combined weight:
![\frac{51}{8}+\frac{37}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B51%7D%7B8%7D%2B%5Cfrac%7B37%7D%7B5%7D)
![=\frac{51\times 5+37\times 8}{40}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B51%5Ctimes%205%2B37%5Ctimes%208%7D%7B40%7D)
![=\frac{255+296}{40}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B255%2B296%7D%7B40%7D)
![=\frac{551}{40}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B551%7D%7B40%7D)
![=13\frac{31}{40}](https://tex.z-dn.net/?f=%3D13%5Cfrac%7B31%7D%7B40%7D)
Therefore, the combined weight is 13 31/40.
