A study of a population of 1,200 frogs revealed that 12 out of every 180 frogs in the popluation have spots on their back Based on the result of this study how many frogs in the population do NOT have a spots on their back? A.80 B.168 C.1.280 D.1,120

Answer 1

Answer: 1120

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
