In an aquarium, the ratio of crabs to fish is 2:7. If there are a total of 36 creatures, how many are crabs? (1 point)

Question

How many are crabs?

Answer 1

Let the number of crabs be \( 2x \) and the number of fish be \( 7x \). The total number of creatures is given by the equation:

\[ 2x + 7x = 36 \]

This simplifies to:

\[ 9x = 36 \]

Now, solve for \( x \):

\[ x = \frac{36}{9} = 4 \]

Now, calculate the number of crabs:

\[ 2x = 2 \times 4 = 8 \]

Thus, the number of crabs is \( \boxed{8} \).
