sayed gave an answer of 6 6/7 for the problem 4 2/7 times 1 3/5, is this a reasonable answer
Yes.
Yes
To determine if Sayed's answer of 6 6/7 for the problem 4 2/7 times 1 3/5 is reasonable, we can perform the multiplication ourselves and compare the result.
To multiply mixed numbers, we follow these steps:
Step 1: Convert the mixed numbers to improper fractions.
4 2/7 = (4 x 7 + 2) / 7 = 30/7
1 3/5 = (1 x 5 + 3) / 5 = 8/5
Step 2: Multiply the numerators and denominators of the fractions.
(30/7) x (8/5) = (30 x 8) / (7 x 5) = 240/35 = 48/7
Step 3: Convert the result back to a mixed number (if possible).
48/7 = 6 6/7
By performing the multiplication ourselves, we obtain the same answer as Sayed, which is 6 6/7. Therefore, Sayed's answer of 6 6/7 is reasonable and correct.
