Answer 2

To solve the expression 2/3 : 4/5, we need to divide the fraction 2/3 by the fraction 4/5.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and the denominator.

So, the expression can be simplified as follows:

2/3 : 4/5 = 2/3 * 5/4

Now, let's simplify the multiplication:

2/3 * 5/4 = (2 * 5) / (3 * 4) = 10/12

The simplified result is 10/12.

However, none of the provided options match this simplified result. The correct simplification is:

2/3 : 4/5 = 10/12

Therefore, none of the options (а, б, в, г) is the correct answer for the given expression.
