An adult polar bear is 8 times longer than a newborn. Newborn= 12 1/2 ft Multiply this by 8. But first you have to turn the fraction 12 1/2 into an improper fraction. To do this you have to multiply the denominator, 2, by the whole number, 12, and add the numerator to the product, which totals to 25. The fraction is 25/2. (25/2 * 8/1)= 100 in simplified. 100 inches= 8 1/3 ft long A= 8 1/3 ft long. For B, you are dividing since you are trying to figure out the length of a newborn, not an adult polar bear. 9/8 turned into a mixed fraction is 1 1/8 ft. But, it asks in inches. B= 13 1/2 inches I know this answer is very long but I hope it helps you understand better! :)
