Given the ratio 3 : 5 : 7:

Calculate the
expected number of items from a population of 7

Ratio Definition

3 : 5 : 7 means that for every

Therefore, our total group is 3 + 5 = 15

Calculate Expected Number of Item A:

Expected Number of Item A  =  3 x 7
  15

Expected Number of Item A  =  21
  15

GCF = 3

Expected Number of Item A  =  7
  5

Expected Number of Item A in Decimal form = 1.4

Calculate Expected Number of Item B:

Expected Number of Item B  =  5 x 7
  15

Expected Number of Item B  =  35
  15

GCF = 5

Expected Number of Item B  =  7
  3

Expected Number of Item B in Decimal form = 2.3333333333333

Calculate Expected Number of Item C:

Expected Number of Item C  =  7 x 7
  15

Expected Number of Item C  =  49
  15

Final Answer

Expected Number of Item A = 1.4
Expected Number of Item B = 2.3333333333333
Expected Number of Item C = 0
