An art teacher has 1,354 ounces of paint. She pours paint into jars that each hold 6 ounces to use during the year. What Is the fewest number of jars she will need, if she uses all of the paint?

Answer 1

1) Zoe's town
April = 5 7/8 inches
May = 2 1/8 inches less than in April

5 7/8 ⇒ ((5*8)+7)/8 = 47/8
2 1/8 ⇒ ((2*8)+1)/8 = 17/8

47/8 - 17/8 = 30/8 ⇒ 3 6/8 ⇒ 3 3/4 inches rainfall in May.

April rainfall : 5 7/8 inches
May rainfall : 3 3/4 inches

Greatest Prime number less than 50 is 47. So, 47 students plus 3 teachers. There is a total of 50 people going on the trip.

1,354 ounces of paint ÷ 6 ounces per jar = 225.66 jars or 226 jars
