ANSWER
2/3
Step-by-step explanation
When we have a multiplication of fractions such as this,

We can simplify the numerators and denominators before solving the product. In this case, since 5 is in the denominator of the first fraction and also in the numerator of the second fraction, it cancels out,

But note that 4 and 6 are both even numbers - i.e. they are divisible by 2, so by dividing both the numerator and the denominator by 2, we will get the simplified answer,

Hence, the product is 2/3.
