(6 8/25 ÷(−1)−(−0.8)·(−0.1))÷(−0.25÷1.25−1 3/5 ÷(−5 1/3 ))

const2013 [10]

Answer:

-64

Step-by-step explanation:

Given expression

$\left(6 \dfrac{8}{25}\div (-1)-(-0.8)\cdot (-0.1)\right)\div\left (-0.25\div 1.25-1 \dfrac{3}{5} \div\left(-5 \dfrac{1}{3} \right)\right)$

Perform all multiplications and divisions:

$6\dfrac{8}{25}\div (-1)=-6\dfrac{8}{25}\\ \\(-0.8)\cdot (-0.1)=0.08\\ \\-0.25\div 1.25=-\dfrac{0.25}{1.25}=-\dfrac{25}{125}=-\dfrac{1}{5}\\ \\1\dfrac{3}{5}\div \left(-5\dfrac{1}{3}\right)=-\dfrac{8}{5}\cdot \dfrac{3}{16}=-\dfrac{3}{10}$

Now subtract results in brackets:

$-6 \dfrac{8}{25}-0.08=-6.32-0.08=-6.4\\ \\-\dfrac{1}{5}-\left(-\dfrac{3}{10}\right)=-0.2+0.3=0.1$

Now, divide:

$-6.4\div 0.1=-\dfrac{6.4}{0.1}=-\dfrac{64}{1}=-64$

The licesnce fee for a car which cost $7,000 is $77. At the same rate what is the license fee for a car that cost $9,200?

artcher [175]

Let 77$ be x percent of 7,000$.

so
$77= \frac{x}{100}*7,000$

$\frac{x}{100}= \frac{77}{7000}= \frac{11}{1000}= \frac{1.1}{100} 
$

so the fee is 1.1% of the cost.

This means the fee for a car costing 9,200$ is

$\frac{1.1}{100}*9,200=1.1*92= 101.2$ $
