Question

Find the value of 8/15×2/13 Although these numbers aren't quite as nice as the ones from the example, the procedure is the same, so the difficulty is the same excepting the ability to perform the calculation in your head. You may choose to use a calculator.

Answer 1

`(16)/(195)`

Explanation:

To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that

`(a)/(b)*(c)/(d)=(a*c)/(b*d)`

Substituting a,b,c and d for 8,15,2 and 13 we obtain that

`(8)/(15)* (2)/(13) =(16)/(195)`
