A zoo has 16 pandas, paired into mates (in the same zoo). Only 25% of the panda couples get pregnant after mating. If they each have one baby, how many panda babies are born?
First divide the number of pandas by 2 to find the number of couples: 16 pandas / 2 = 
<gadget id="calculator">16/2</gadget>
<output>8</output>
8 panda couples.
Then multiply that number by 25% to find the number of babies: 8 panda couples * 25% = 
<gadget id="calculator">8*25*.01</gadget>
<output>2</output>
2 panda babies.
