The ratio of laptops tablets in the stock room of a store is 13 : 17. If there are a total of 90 laptops
and tablets in the stock room, how many laptops are in the stock room?
~~~~~~~~~~~~~~ 


Group laptops and tablets in sets, combining 13 laptops and 17 tablets in each set.


The number of items in each set is 13+17 = 30.


Hence, the number of sets is  90:30 = 3.


It means that there are 3*13 = 39 laptops and 3*17 = 51 tablets.    ANSWER
