Did you really think someone would write you a whole essay just for fun
A.) 75 x 60 = 4500 in an hour
4500 x 24 = 108000 in a day
108000 x 365 = 39420000 in a year
39420000 x 45 = <span>1,773,900,000 in 45 years
</span>B.)2200800 / 75 = 29344 mins
29344 / 60 = <span>489.066666667 hours
</span>489.066666667 / 24 = 20.37777778
you get it
800000000+40000000+5000000+300000+30000+3000+100+20+9
