    According to the problem's info, we have:

    (1 + 2 + 4) pieces of fabric = 1bug

    (7) pieces of fabric = 1bug

    so we know for each bug Missy uses 7 pieces of fabric (of different shapes).

    Then, if she uses 70 pieces (7*10) of fabric, those are 10 bugs (1*10) built.

    so we have to multiply by 10 the amount of pieces used in one bug:

    hexagonal = 1*10 = 10

    rectangular = 2*10 = 20

    triangular = 4*10 = 40

    which give us 70 pieces total.

    10 hexagonal

    20 rectangular

    40 triangular

    First add the 2+1+4=7

    The divide 70 by 7 to get 10 the times each of the shapes by ten
