​

Answer 1

Answer:

68, 45 1/9.

Step-by-step explanation (juice):

28=2×2×2×3 1/2, so 2 3/7×2×2×2×3 1/2=2 3/7×28. 2 3/7×2=4 6/7, and 4 6/7×2=8 12/7. Next, 8 12/7×2=16 24/7. Turn both 3 1/2 and 16 24/7 into improper fractions. 7/2×136/7=68.

Step-by-step explanation (rice):

6 4/9×7=42 28/9, turn it into a mixed number and you're done. 45 1/9.
