simplify 120(1+10.5)^{(-1)}

Solution

simplify

120 \cdot (1 + 1 \cdot 0.5)^{(- 1)}

Solution

80

Solution steps

120 (1 + 1 \cdot 0.5)^{(- 1)}

Apply exponent rule:

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

= 120 \cdot \frac{1}{( 1 + 1 \cdot 0.5 )}

1 + 1 \cdot 0.5 = 1.5

= 120 \cdot \frac{1}{1.5}

Multiply fractions:

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

= \frac{1 \cdot 120}{1.5}

Multiply the numbers:

1 \cdot 120 = 120

= \frac{120}{1.5}

Divide the numbers:

\frac{120}{1.5} = 80

= 80
