Answer:81/20 or 4 1/20
Explanation:
To solve this problem, we need to use the rules of multiplication and fractions.
First, we need to convert the mixed numbers to improper fractions:
3 and 3/5 = (5 * 3 + 3) / 5 = 18/5
2 and 1/4 = (4 * 2 + 1) / 4 = 9/4
Now we can multiply the two fractions:
(18/5) * (9/4)
To simplify this expression, we can cancel out any common factors between the numerators and denominators:
(18/5) * (9/4) = (2 * 9)/(5 * 2) * (9/4) = 9/5 * 9/4
Then, we can multiply the numerators and denominators separately:
9/5 * 9/4 = (9 * 9) / (5 * 4) = 81/20
Therefore, 3 and 3/5 times 2 and 1/4 is equal to 81/20 or 4 1/20 as a mixed number.
