Use the data table for 16-18. 16. Kwame reads that the mass of an average elephant's brain is \( 3 \frac{4}{10} \) kilograms greater than an average man's brain. How many kilograms is an average elephant's brain?

An average man's brain weighs approximately 1.4 kilograms. If we add \( 3 \frac{4}{10} \) kilograms (or 3.4 kilograms) to this, we can find the mass of an average elephant's brain. So, \( 1.4 + 3.4 = 4.8 \) kilograms. Therefore, the average elephant's brain weighs about 4.8 kilograms! Interestingly, elephant brains are enormous, not just when compared to humans but within the animal kingdom as well! An adult elephant's brain can weigh between 4.5 to 5.5 kilograms, which is vital not only for their size but for their advanced social behaviors, memory, and intelligence. Skillful animal lovers often marvel at the intelligence of elephants, which features problem-solving abilities and emotional depth. Elephants are known to exhibit behaviors such as mourning their dead and forming close-knit family bonds. This fascinating cognitive function links strikingly with their brain's mass and complexity!
