A country has 221 mobile cellular telephones per 250 inhabitants.
If the country's population is about 2,800,000 how many mobile cellular
telephones does the country have?
:
let t = no. of telephones
:
Write a ratio equation
221%2F250 = t%2F2800000
Cross multiply
250t = 221*2800000
:
250t = 618800000
t = 61880000%2F250
t = 2,475,200 telephones
