#1 Convert the percents to decimals and fractions
46% = 0.46 = 46/100 = 23/50
18% = 0.18 = 18/100 = 9/50
#4 An astronaut spends 53% of the day working, 0.1 of the day eating, 3/10 of the day sleeping, and the rest of the day exercising. Order the events by duration from least to greatest. 53% = 0.53 3/10 = 0.3
0.1 + 0.3 + 0.53 = 0.93 100 - 0.93 = 0.07
Exercising (0.07), Eating (0.1), Sleeping (0.3), Working (0.53)
#2 Convert the decimals to percents and fractions
.7 = 70% = 7/10
1.45 = 145% = 1 and 45/100 = 1 and 9/20
#3 Convert the fractions to decimals and percents
5/9 = 0.55555… = 55.555…% = about 56%
7/2000 = 0.0035 = 0.35%
#5 A band plays one concert in Arizona, one concert in California, and one concert in Georgia. In California, the band earned 3/2 the profit that they earned in Arizona. Of the total profit earned by the band, 32% is earned in Arizona. How many times more money did the band earn at the most profitable concert than at the least profitable concert?
3/2 x 32% = 48% 32% + 48% = 80% 100% - 80% = 20%
Arizona = 32% California = 48% Georgia = 20%
48%/20% = 4.8 4.8 times more money
