Collector A #24# stamps
Collector B #30# stamps
Collector C #36# stamps

Explanation:

We can solve this by using the #4:5:6# ratio and assigning the unit value #n# to each part of the ratio.

Collector A #=4n#
Collector B #=5n#
Collector C #=6n#

Together the collectors have #90# stamps.

#4n +5n + 6n = 90#

Combine like terms.

#15n = 90#

Use the multiplicative inverse to isolate the variable.

#((cancel15)n)/(cancel15) = 90/15#

#n = 6#

Collector A #=4(6) = 24#
Collector B #=5(6) = 30#
Collector C #=6(6) = 36#
