Answer 1

Q1a: a year has 12 months therefore 5 months is equal to 5/12 of a year or 0.42 year

Q1b: a year has 365 days so 75 days is equalt 75/365 or 0.2 year.

Q1c: a year has 52 weeks so 18 weeks is equal to 28/52 or 0.54 year.

Q2a: interest rate per week = 12/52 = 0.23% (52 is the # of weeks in a year)

Q2b: there are 26 biweekly periods in a year so the answer is 8/26 = 0.308%

Q2c: there are 12 monthly periods in a year so the answer is 6/12 = 0.5%.
