Table 1 Fill in the blank: Choose a word from the bank below to fill in the blank space. Not all the words will be used and you may only use each word once. Word Bank: natural numbers negative rational number positive integers whole numbers irrational number zero Any number that can be written as a fraction is called a/an _____________. A non repeating, non terminating decimal represents a/an _______________. All whole number and their opposites are called ______________. _______________ is a whole number but NOT a natural number. Answer each question carefully. Be sure to show all work when appropriate. Circle the choice that shows all of the number systems to which the number 0 belongs to. A. rational B. rational, integers C. rational, integers, whole D. rational, integers, whole, and counting 6) Which of the following fractions is NOT repeating decimal?
