Answer:
1, 2, and 4.
Explanation:
1) 38.59 divided by 17 = 2.27, and 2.27 times 3 = 6.81
2) 112 divided by 1.75 (the 0.75 is 45 minutes out of 60) = 64.
3) 8.40 divided by 24 (two dozen) = 0.35, not 0.70
4) 7.74 divided by 6 = 1.29, and 1.29 times 7 is 9.03
5) 256.5 divided by 4.166667 (roughly 4 hours and 10 minutes in decimal form) = 61.55999995, not 57.
