Questions & Step-by-Step Solutions
In a pie chart showing the types of pets owned by families, 40% have dogs, 30% have cats, 20% have birds, and 10% have reptiles. If there are 80 families surveyed, how many have dogs?
Step 1: Understand that 40% means 40 out of every 100 parts.
Step 2: Know that there are 80 families surveyed.
Step 3: To find out how many families have dogs, calculate 40% of 80.
Step 4: Convert 40% to a decimal by dividing 40 by 100, which gives you 0.40.
Step 5: Multiply 0.40 by 80 to find the number of families with dogs: 0.40 * 80.
