Question

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?

Answer 1

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.
