e : f = 2 : 3 and f : g = 5 : 4 Work out e : g Give your answer in its simplest form.

Try and make the numbers representing f in both ratios the samee : f = 10 : 15 is you multiply both numbers by 5f : g = 15 : 12 if you multiply both numbers by 3Now f is the same number so you can say:e : f : g = 10 : 15 : 12Looking at just e and g, this means e : g = 10 : 12When you simplify by dividing both numbers by 2, you get:e : g = 5 : 6
