If the zookeeper had 100 pairs of animals in her zoo and if two pairs of babies are born for each and every one of the original animals, and then sadly 23 animals don’t survive, how many animals do you have left in total?

177 animals

Step-by-step explanation:

So, you have 100 animals, multiply by 2 because you have 2 animals born PER original animal.

You then have 200 animals, but 23 don't survive. therefore you subtract the 23 from 200.

you will have 177 animals

287

Step-by-step explanation:

Since 2 pairs of babies are born from each and every one of the animals, that means there are 200 babies. You add 100 to 200 and get 300 and then subtract 23, which gives 287 animals left.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
