Given:
1 inch = 2.54 cm
To find:
The number of inches, n, in 10 cm.
Solution:
We have,
1 inch = 2.54 cm
On dividing both sides by 2.54, we get
[tex]\dfrac{1}{2.54}[/tex] inch = 1 cm
On multiplying both sides by 10, we get
[tex]\dfrac{1}{2.54}\times 10[/tex] inch = 10 cm
Now, number of inches n in 10 cm is
[tex]n=\dfrac{1}{2.54}\times 10[/tex]
[tex]n=3.93700787402[/tex]
[tex]n\approx 3.9[/tex]
Therefore, the number of inches in 10 cm is 3.9.
