Answer:

\boxed{5 : 2}  

Step-by-step explanation:

QUESTION:

If 3A = 5B and 4B = 6C; find A: C.

GIVEN :

  • 3A = 5B

⇒A = \frac{5}{3}B                                .................. {\boxed1}

  • 4B = 6C

⇒C = \frac{4}{6}B

   C= \frac{2}{3}B                               .....................{\boxed2}

TO Find:

A : C

Solution:

A : C = \frac{5}{3}B  :  \frac{2}{3}B

       = \frac{ \frac{5}{3} B}{\frac{2}{3} B}

       = \frac{\frac{5}{3} \not{B}}{\frac{2}{3}\not{B}}

       =\dfrac{5}{3} \times \dfrac{3}{2}

      = {\frac{5}{2}

      = \boxed{5 : 2}
