Gabby, Penelope, Bobby and Zoe shared some stamps. Gabby and Penelope took
14 of the total number of stamps while Bobby and Zoe took the rest. Penelope had four times as many stamps as Gabby and Zoe had 24 stamps. Given that Zoe had twice as many stamps as Penelope, how many stamps were there altogether?

Number of stamps that Penelope had is repeated. Make the number of stamps that Penelope had the same. LCM of 4 and 1 is 4.
Number of stamps that Zoe had = 8 u
8 u = 24
1 u = 24 ÷ 8 = 3
Total number of stamps
= 20 u
= 20 x 3
= 60
Answer(s): 60
