24. 47 jars
25. 81 pumpkins
26. 98 coins
2. 94 high ÷ .03 thick = 98 coins
27. 18.25 miles
264.625 miles ÷ 14.5 bars = 18.25 miles
28. $0.00
$1240 ÷ 100 = $12.40 for each student at School A
School B split the $12.40 into 100 parts: $12.40 ÷ 100= $0.124 or 12.4 cents
School C split the 12.4 cents into 100 parts: .124 ÷ 100= $0.00124
(Rounds to "0" cents)
29. 248.53 Earth years
90,777.6 days ÷ 365.26 days = 248.5287
