While this can appear intimidating at first, the key to simplifying this expression is through factorising and identifying common factors. Let's start off by factorising the denominator as this is simpler...
Using BODMAS:4*5 = 203+20 = 23
C = (F-32)*(5/9)(9/5)C = F-32F = (9/5)C + 32
Blue:Red = 4:54+5 = 945/9=5As the ration is 4:5, this means that there are 5*5 = 25 red counters in a bag
