Hiroshi made a mistake in his calculation.
To multiply fractions, we multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator. So, multiplying 2/7 by 3 should give us (2/1) * (3/7) = 6/7.
Therefore, Hiroshi should have gotten the answer 6/7.
Hiroshi multiplied 2/7 times 3 and got 6/21 . What final answer should he have gotten?(1 point)
