Kelvin has 14 more foreign stamps than local stamp.
Step-by-step explanation:
Given,
Total number of stamps = 112
Ratio of local stamps to foreign stamps = 7:9
Let,
The number of local stamps = 7x
The number of foreign stamps = 9x
Therefore,
Number of local stamps = 7x = 7(7) = 49
Number of foreign stamps = 9x = 9(7) = 63
Difference = 63 - 49 = 14
Kelvin has 14 more foreign stamps than local stamp.
