simplify 2*10^{-7}((10)/(0.07)+(20)/(0.02))

simplify

2 \cdot 1 0^{- 7} (\frac{10}{0.07} + \frac{20}{0.02})

0.00022 \dots

Solution steps

2 \cdot 1 0^{- 7} (\frac{10}{0.07} + \frac{20}{0.02})

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= 2 \cdot \frac{1}{1 0 ^{7}} (\frac{10}{0.07} + \frac{20}{0.02})

Join

\frac{10}{0.07} + \frac{20}{0.02} : 1142.85714 \dots

= 2 \cdot 1142.85714 \dots \cdot \frac{1}{1 0 ^{7}}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= 1142.85714 \dots \cdot \frac{1 \cdot 2}{1 0 ^{7}}

\frac{1 \cdot 2}{1 0 ^{7}} = \frac{1}{5000000}

= 1142.85714 \dots \cdot \frac{1}{5000000}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot 1142.85714 \dots}{5000000}

Multiply the numbers:

1 \cdot 1142.85714 \dots = 1142.85714 \dots

= \frac{1142.85714 \dots}{5000000}

Divide the numbers:

\frac{1142.85714 \dots}{5000000} = 0.00022 \dots

= 0.00022 \dots

\frac{- 8}{- 2}
