y varies directly to x,
By Ratio & Proportion:
Y%5B1%5D=unknown; X%5B2%5D=3%2F2
X%5B1%5D=54; Y%5B2%5D=1%2F4
Y%5B1%5D%2FX%5B1%5D=Y%5B2%5D%2FX%5B2%5D
Y%5B1%5D=Y%5B2%5DX%5B1%5D%2FX%5B2%5D
Y%5B1%5D=%281%2F4%29%2854%29%2F%283%2F2%29
Y%5B1%5D=%281%2F4%29%2854%29%282%2F3%29
Y%5B1%5D=%281%2Fcross%284%292%29%2854%29%28cross%282%291%2F3%29=54%2F%282%2A3%29
