Respuesta :

Answer: 1120

Step-by-step explanation:

Since 12 out of every 180 frogs in the popluation have spots on their back, this means that (180 - 12) = 168 do not have spot on their back. This can be represented in a fraction as:.= 168/180 = 14 / 15

With a study of a population of 1,200 frogs, the number of frogs that do not have a spots on their back will be:

= 14/15 × 1200

= 1120
