Question

A display at the natural science museum contains 21 plant and animal fossils 4/7 of the fossils in the display are animal fossils.how many fossils in the display are animal fossils??

Answer 1

if there is 21 plant and animal fossils and 4/7 are animal fossils then 3/7 of the fossils are plant fossils. Now just figure out how much 1/7 is.

21/7 = 3

so every 1/7 is 3

hope that helps you and good luck on finding the rest of it :)

Answer 2

There are 12 animal fossils. I found this by dividing 21 by 7 and multiplying that answer by 4.
