Answer:

Explanation:
Let's first add 16/25 with 3/10. To do that, we look for the least common multiple between 25 and 10, which is 50 and we put it in the denominator. Then, we have to compute (50/25)*16, which is equal to 32, and add it to (50/10)*3, which is equal to 15
On the other hand, to the non-fraction terms, we just add them. So, 632 + 32 = 664
Finally, the result is 664 47/50
