Answer:

$-\frac{28}{99}$

Step-by-step explanation:

To divide a fraction by a fraction, flip the second fraction and change the divide sign into a multiplication sign.

$\frac{4}{9}\div -\left(\frac{11}{7}\right)=\frac{4}{9} *-\frac{7}{11}$

Multiply:

$-\frac{4*7}{9*11}$

$-\frac{28}{99}$

A circle is 360 degrees

Arc EF is 146 degrees

EF + EDF = full circle

A student invested 80% of her savings in the stock market. If she invested $5,200, what are her total savings in dollars?

Leokris [45]

One way to approach this is to know that $5200 is 80% of her savings, so if we divide 5200 by 8 we will get 10% of her savings. 5200/8 = $650.
We can then multiply this by 10 to get 100%, or her total, savings (because 10*10=100)
So, $650*10= $6500
The total savings in dollars is $6500
