##11/8##
We can write a percentage as a fraction by taking the percentage and dividing it by 100. In this case:
##137.5% = 137.5/100##
We want to simplify our fraction now and the first step is to get rid of the decimals by multiplying both top and bottom by ##2##:
##= 275/200##
By looking at this fraction you might notice that both ##275## and ##200## are divisible by ##5## so let’s divide both by ##5##
##=55/40##
We notice again that ##55## and ##40## are divisible by ##5## so we divide both by ##5## again
##=11/8##
