Step-by-step explanation:

Start-up costs of $150,000.

For the 50 tons of cooper.

Is 16/17 and 8/32 proportional

pickupchik [31]

16 has several factors, BUT bear in mind that 17 is a prime number, it has no factors other 1, so 16/17 cannot be simplified,

$\bf \cfrac{16}{17}\qquad \cfrac{8}{32}\implies \cfrac{16}{17}\qquad \cfrac{1}{4}\implies \cfrac{16}{17}~\ne~ \cfrac{1}{4}$
