Simply
2 whole number 3/8+1whole number 2/5
To add these two mixed numbers, we first need to convert both to improper fractions.
2 whole number 3/8 = 2 x 8/8 + 3/8 = 16/8 + 3/8 = 19/8
1 whole number 2/5 = 1 x 5/5 + 2/5 = 5/5 + 2/5 = 7/5
Now we can add the two fractions:
19/8 + 7/5 = (95/40) + (56/40) = 151/40
Finally, we can convert this improper fraction back to a mixed number:
151/40 = 3 whole number 31/40
Therefore, 2 whole number 3/8 + 1 whole number 2/5 = 3 whole number 31/40.
