How do I express the following as a fractional part of a year?
3 month
55 days
1 month
7 months
120 days

See below.

Step-by-step explanation:

A year has 12 months and 365 days.

3 months: 3/12 year = 1/4 year

55 days: 55/365 year = 11/73 year

1 month: 1/12 year

7 months = 7/12 year

120 days = 120/365 year = 24/73 year

{decimal} 6 = (6 × 8⁰) = 6{decimal}141 = (1 × 8²) + (4 × 8¹) + (1 × 8⁰) = 97{decimal} 374 = (3 × 8²) + (7 × 8¹) + (4 × 8⁰) = 252{decimal}304 = (3 × 8²) + (0 × 8¹) + (4 × 8⁰) = 196{decimal}602 = (6 × 8²) + (0 × 8¹) + (2 × 8⁰) = 386{decimal}263 = (2 × 8²) + (6 × 8¹) + (3 × 8⁰) = 179{decimal}202 = (2 × 8²) + (0 × 8¹) + (2 × 8⁰) = 130{decimal}157 = (1 × 8²) + (5 × 8¹) + (7 × 8⁰) = 111
