Question

How do i solve this equation a over c is equal to d over a to solve for a

Answer 1

$\frac{a}{c} = \frac{d}{r} \\ \\ a \times r = c \times d \\ \\ a= \frac{cd}{r}\\ \\ \boxed{ \red{ \bold{a= \frac{cd}{r} }}}$

Answer 2

Hey there!!

Given equation :

a / c = d / r

Cross multiplication :

... ar = cd

Divide by r on both sides

... a = cd / r

Hope this helps!
