<span>Let's solve how many whole minutes does it take 10 000 viruses to grow to 1 million if their population doubles every 15 minutes. => 10 000 x n = 1 000 000 => 1 000 000 / 10 000 = 100 times => 100 times * 15 minutes = 1500 minutes to make 1 million viruses
42/56 = 56/64 cross multiply (56)(56) = (42)(64) 3136 = 2688...(incorrect)...these are not proportional
proportions are nothing but equivalent fractions 42/56 = 3/4 56/64 = 7/8 as u can see, they are not equivalent fractions...so they are not proportional
