Question

$3.4 \times {10}^{ - 4} = x (100 \times {10}^{ - 4} - 50 \times {10}^{ - 4} )$
​

Answer 1

HEY MATE THE ANSWER IS : 17/250

SOLVING STEPS :

$3.4 \times 10 ^{ - 4} = x(100 \times 10 ^{ - 4} - 50 \times 10 ^{ - 4} )$

$\frac{17}{5} \times \frac{1}{10 ^{ - 4} } = x \times 50 \times 10 ^{ - 4}$

$\frac{17}{5 \times 10 ^{ - 4} } = x \times 50 \times \frac{1}{10 ^{ - 4} }$

$\frac{17}{5 \times 10000} = \frac{50x}{10 ^{4} }$

$\frac{17}{50000} = \frac{50x}{10000}$

$\frac{17}{50000} = \frac{x}{200}$

$3400 = 50000x$

$50000x = 3400$

$x = \frac{3400}{50000}$

$x = \frac{17}{250}$
