Answer 2

$frac{95 times 4 times 0.00014}{700 times 0.19} + frac{0.89 times 0.25 times 72}{45 times 7.8} = frac{95 times 0.0014}{175 times 0.19} + frac{0.89 times 8}{5 times 31.2} = frac{19 times 0.0014}{35 times 0.19} + frac{7.12}{156} = frac{0.0266}{35 times 0.19} + frac{ frac{178}{25} }{156} = frac{0.14}{35} + frac{89}{1950} = 0.004 + frac{89}{1950} = frac{1}{250} + frac{89}{1950} = frac{242}{4875}$
