Question 7 Is 10% of a day longer than 1% of a week? Create such questions and challenge your peers.Let’s convert both days & weeks into hours 10% of a day Now, 1 day has 24 hours So, 1 day = 24 hours Thus, we can write 10% of a day = 10% × 1 day = 10% × 24 hours = 𝟏𝟎/𝟏𝟎𝟎 × 24 hours = 1/10 × 24 = 2.4 hours 1% of a week Now, 1 week has 7 days and 1 day has 24 hours So, 1 week = 7 × 1 day = 7 × 24 hours Thus, we can write 1% of a week = 1% × 1 week = 1% × 7 × 24 hours = 𝟏/𝟏𝟎𝟎 × 7 × 24 hours = 168/100 = 1.68 hours Thus, our answer is Yes, 10% of a day (2.4h) is longer than 1% of a week (1.68h).
