If a marine reserve has 250 species of fish and 40% are coral reef species, how many coral reef species are there?

Step 1: Understand that we need to find 40% of the total number of fish species.
Step 2: Identify the total number of fish species, which is 250.
Step 3: Convert the percentage (40%) into a decimal. To do this, divide 40 by 100, which gives you 0.40.
Step 4: Multiply the total number of fish species (250) by the decimal (0.40). This means you calculate 0.40 * 250.
Step 5: Perform the multiplication: 0.40 * 250 = 100.
Step 6: Conclude that there are 100 coral reef species in the marine reserve.
