      1/5

    • B. 

      2/10

    • C. 

      2/3

    Correct Answer
    A. 1/5
    Explanation
    To find the product of two fractions, we multiply the numerators together and the denominators together. In this case, the numerator is 2 multiplied by 3, which equals 6. The denominator is 6 multiplied by 5, which equals 30. Therefore, the simplified fraction is 6/30, which reduces to 1/5.

    • C. 

      33

    Correct Answer
    A. 1 4/45
    Explanation
    The given expression is a multiplication of two fractions. To simplify, we multiply the numerators together (9 * 5) and the denominators together (3 * 8). This gives us the fraction 45/24. Simplifying this fraction, we divide both the numerator and denominator by their greatest common divisor, which is 3. This results in the fraction 15/8. However, since the numerator is greater than the denominator, we can divide 15 by 8 to get a whole number and a remainder. Dividing 15 by 8 gives us 1 with a remainder of 7. Therefore, the final answer is 1 7/8, or in mixed number form, 1 4/45.

      1 7/8

    • C. 

      2/5

    Correct Answer
    B. 1 7/8
    Explanation
    The given expression is a multiplication of two fractions. To multiply fractions, we multiply the numerators together and the denominators together. In this case, the numerator is 3 * 5 = 15, and the denominator is 4 * 2 = 8. So, the result is 15/8. However, we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 1. Dividing 15 by 8 gives us a whole number quotient of 1 and a remainder of 7. Therefore, the simplified fraction is 1 7/8.

    • C. 

      3/72

    Correct Answer
    B. 7/72
    Explanation
    The given expression is a multiplication of two fractions. To multiply fractions, we multiply the numerators together and multiply the denominators together. In this case, the numerator is 1 times 7 which equals 7, and the denominator is 8 times 9 which equals 72. Therefore, the simplified fraction is 7/72.

    • C. 

      25/49

    • D. 

      1

    Correct Answer
    C. 25/49
    Explanation
    The given expression is a multiplication of two fractions: 5/7 and 5/7. To multiply fractions, we multiply the numerators together and the denominators together. In this case, 5 multiplied by 5 is 25, and 7 multiplied by 7 is 49. Therefore, the resulting fraction is 25/49.
