Penguin Adaptations
Learning Objective
I can describe the physical adaptations that help penguins survive in their environment.
Key Concepts
When adding fractions with unlike denominators, the first step is to find a common denominator by determining the least common multiple of the denominators.
To rename a fraction, multiply both the numerator and the denominator by the same number to create an equivalent fraction with the common denominator.
Once the fractions have a common denominator, add the numerators and keep the denominator the same, then simplify the fraction if possible.
