Every evening is 1/4 of the people so 1/4 of 440 is 1/4 * 440 = 110 people five or six nights is 2/5 of the people so 2/5 of 440 is 2/5 * 440 = 176 people four nights or less - two ways to do this one. If there are 440 people then 440 - 110 - 176 = 154 people or 1/4 + 2/5 = 5/20 + 8/20 = 13/20 so the rest of the 20/20 is 7/20 so 7/20 of the people are 4 or less so 7/20 of 440 is 7/20 * 440 = 154 people
