Step-by-step explanation:

=>we know that in 1 dozen there is 12 things

=>so, 10 dozen 10 ×12 =120

=>there are two things or article in pair

=>so, 80×2 =160

=> and there ratio = 120/160

=> 0.75 is the answer

Answer:

Since, 1 dozen = 12

Therefore, 10 dozen = 12 * 10= 120

There are two articles.

So, 80*2 = 160

There ratio = 120:160 = 3:4
