Full question:
Paleo museum has 60% dinosaurs fossils. 60% of the dinosaurs are herbivores so they only eat plants. How many of the dinosaurs at paleo museum are herbivores?
Answer:
60% of 0.60x= 36 ,assuming 100 total fossils in Paleo museum
Explanation:
Let total fossils in Paleo museum = x
60% dinosaur fossils in Paleo museum = 60% of x=60/100*x=0.60x
60% of the dinosaurs are herbivores hence 60% of 0.60x
Plug in 100 total fossils:
So let's assume x= 100 total fossils in museum
Dinosaur fossils = 0.60x = 0.60*100= 60 dinosaur fossils
There are 60% herbivore dinosaurs hence 60% of dinosaur fossils are herbivores = 0.60*60 = 36
Therefore there are 36 herbivore dinosaurs in Paleo museum, assuming there are 100 total fossils in the museum
