Question

60% of a museum’s fossils are from the Jurassic Period. If the number of fossils from the Jurassic period is 15, what is the total number of fossils at the museum?

Answer 1

Answer : The total number of fossils at the museum are, 25

Step-by-step explanation :

As we are given that 60% of a museum’s fossils are from the Jurassic Period.

Let the total number of fossils at the museum be, 'x'

Given:

Number of fossils from the Jurassic period = 15

The % of a museum’s fossils are from the Jurassic Period = 60%

Thus, the expression will be:

$\frac{15}{x}\times 100=60$

By solving the term 'x' we get:

$x=\frac{15}{60}\times 100$

$x=25$

Thus, the total number of fossils at the museum are, 25
