Question

kelvin has 112 stamps in all. The ratio of the number of local stamps to the number of foreign stamps is 7:9. How many more foreign stamps than local stamps does Kelvin have?

Answer 1

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

$7x+9x=112\\16x=112\\x=7$

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.

Answer 2

Answer:

14

Step-by-step explanation:

7+9=16

112/16=7

7x=7*7=49

9x=9*7=63

63-49=14

Or

9-7=2

x=112/16=7

x=7*2=14
