Mia is 6973920 minutes old. convert her age to years days and months assuming that a year has 365 days and a month has 30 days

If 1 mo = 30 days:   13 yr + 5 mo + 5 days

If 1 yr   = 365 days: 13 yr + 3 mo + 7days

Step-by-step explanation:

The two conversion factors are incompatible, so I will so both calculations.

1. Assume that a month has 30 days.

Age = 6 973 920 min     Convert to hours

Age = 6 973 920 min × (1 h/60 min)

Age = 116 232 h              Convert to days

Age = 116 232 h × (1 day/24 h)

Age = 4843 days             Convert to months

Age = 4843 days × (1 mo/30 days)

Age = 161¹³/₃₀ mo

Age = 161 mo 13 days     Convert months to years

Age = 161 mo × (1 yr/12 mo) + 13 days

Age = 13⁵/₁₂ yr  + 13 days

Age = 13 yr + 5 mo + 5 days

Mia is 13 years, five months, and five days old.

2. Assume that a year has 365 days

     Age = 4843 days          Convert to years

     Age = 4843 days  × (1 yr/365 days)

     Age = 13.2685 yr         Convert the decimal part to months

Months = 0.2685 yr × (12 mo/1 yr)  

Months = 3.222 mo           Convert the decimal portion to days

   Days = 0.222 mo × (30 da/1 mo)

   Days = 7

Age   = 13 yr + 3 mo + 7 days

Mia is 13 years, three months, and seven days old.
