Answer 2

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