First find how they got 10 inches out of 25 centimeters.
25/10 = 2.5
This means that they divided 25 by 2.5 to get 10, and this pattern will continue throughout the whole table.
105 × 2.5 = 42
There are about 42 inches in 105 centimeters.
Another way to do this is there are 0.39 inches in 1 centimeter.
105 × 0.39 = 40.95
This rounds to 41.
This answer is probably better.
