You are making a necklace that is 9 inches long. You use 6 beads for each inch. What integer is the change in your supply of beads after making the necklace?

To answer this question we first must know the definition of an integer. An Integer is a whole number. 1, 10, 100 are all integers. 1.3 and 0.75 are not. So now we must multiply the number of beads per inch by the total number of inches: The question states you use 6 beads for each inch. So 6 beads per inch multiplied by 9 inches is 54 beads. So your supply changes by 54 beads.
