Answer 1

Answer:

Step-by-step explanation:

19 - you would divide number of beads by beads per bracelet to get number of bracelets

blue = 258/6 = 43

silver = 428/9 = 47.56, round down because we're looking at complete bracelets = 47

rose = 102/3 = 34

white = 258/7 =36.86, round down again = 36

20 - they can make 43 + 47 + 34 + 36 = 160 bracelets before they run out, and they will run out of rose first since it has the smallest number of bracelets

21 - multiply num of beads by num of bracelets for each color and add them up

blue = 6 * 7 = 42

silver = 9 * 7 = 63

rose = 3 * 7 = 21

white = 7 * 7 = 49

42 + 63 + 21 + 49 = 175
