in a fish tank 1/2 of the fish I have a red stripe on them. If 10 of the fish have red stripes how many total fish are in the tank

Answer 1

If 1/2 of the fish in the tank have red stripes and there are 10 fish with red stripes, you can find the total number of fish in the tank by setting up the equation:

Let \( x \) be the total number of fish in the tank.

Since half of them have red stripes, we have:

\[ \frac{1}{2}x = 10 \]

To find \( x \), multiply both sides of the equation by 2:

\[ x = 10 \times 2 \]

\[ x = 20 \]

So, there are 20 fish in total in the tank.
