Question

Let's see who can answer first What's the combination? I'll give you a clue. It starts with a fraction with the denominator of 2. You'll need to simplify once again Because the numerator in this fraction is 10. What is the answer?

Answer 1

5

Explanation:

Referring to the clue given, the denominator of the fraction is 2 and the numerator of the fraction is 10.

So, the fractional number is

`\frac {\text{Numerator}}{\text{Denominator}}=(10)/(2)`

`=(2*5)/(2)` [ prime factorization of 10 = 2 x 5]

On canceling the common factor of numerator and denominator, i.e 2, we have

`(2*5)/(2)=5`

Hence, the required value is 5.
