How do you find the ratio of the following in the simplest form: (i) 2 dozens to 3 scores (ii) 1 kg 200g and 1 kg 800g (iii) 864 and 60 (iv) 1 .5 kg yo 15 g (v) x^2 + 2x + 1 and x^2 - x -2?

Answer 1

(i) (2*12)/(3*20) = 24/60 = 2/5

(ii) (1000 g + 200g) / (1000 g + 800g) = 1200g/ 1800 g = 12/18 = 2/3

(iii) 864/60 = 216/15 = 72/5

(iv) 1500 grams / 15 g = 100 / 1

(v) { (x+1)(x+1)} / {(x - 2)(x + 1 )} =

(x+1)/(x-2) provided x is not 2
