Answer 1

Answer:

$\frac{a}{b} =\frac{5}{4}$

Step-by-step explanation:

Given:  

          $\frac{15}{a} =\frac{12}{b}$

To find the ratio of 'a' and 'b', just cross-multiply the given fraction to make the form of 'a' ratio 'b'.

                     $\frac{15}{a} =\frac{12}{b}$

                    $\frac{15}{12} =\frac{a}{b}$

Dividing numerator and denominator by a common value i.e 3, for simplest form

                  $\frac{a}{b} =\frac{5}{4}$
