Question

A: b = 5:9 and b: c = 6:7. Find the simplest form
of the ratio a:c.

Answer 1

a:b = 5:9
b:c = 6:7

Multiply quantity a and b in a:b by 6

(ax6) : (bx6) = (5x6):(9x6) = 30:54

Multiply quantity b and c in b:c by 9
(bx9):(cx9) = (6x9):(7x9) = 54 : 63

So, a:b:c = 30:54:63

And so the ratio a:c = 30:63

Simplify : divide by 3, 10:21.
