What is 3 1/5 times 2 2/5 in lowest terms?
Correct Answer
C. 7 17/25
Explanation
To find the product of 3 1/5 and 2 2/5, we multiply the whole numbers first, which gives us 6. Then, we multiply the fractions. 1/5 multiplied by 2/5 is 2/25. Adding the whole numbers and fractions together, we get 6 + 2/25, which can be simplified to 6 2/25. Since 2/25 cannot be further reduced, the answer is in lowest terms. Therefore, the correct answer is 7 17/25.
