In order to determine what is the result of the given division, consider 2 as the fraction 2/1.
Then, you have a division between two fractions:
(1/10) ÷ (2/1)
the previous division can be written as a product by inverting numerator and denominator of the second fraction 2/1, just as follow:
(1/10) ÷ (2/1) = (1/10)x(1/2)
remind that multiplication between fraction is equal to the product between numeratos divided by the product between denominators.
(1/10) x (1/2) = 1/20
Hence, the result is 1/20
