c. 6 3/15
10 2/15
To multiply the mixed numbers 1 3/5 and 6 1/3, we first convert them to improper fractions:
1 3/5 = 8/5
6 1/3 = 19/3
Now, we multiply the fractions:
(8/5) * (19/3) = (8*19) / (5*3) = 152 / 15
Next, we convert the improper fraction back to a mixed number:
152 / 15 = 10 2/15
Therefore, the product of 1 3/5 and 6 1/3 is equal to 10 2/15.
The correct answer is d. 10 2/15.
