Final answer:
To reduce the fraction 4/7 x 3/8, you multiply the numerators and denominators of the two fractions to get the resulting fraction 12/56.
Step-by-step explanation:
To reduce the fraction 4/7 x 3/8, you need to multiply the numerators (the top numbers) and multiply the denominators (the bottom numbers) of the two fractions. So, the numerator of the resulting fraction is 4 x 3 = 12, and the denominator is 7 x 8 = 56. Therefore, the reduced fraction is 12/56.
