Simplify the following expression using only positive exponents. Help please!?

sammy [17]

$\bf a^{-{ n}} \implies \cfrac{1}{a^{ n}}\qquad \qquad

\cfrac{1}{a^{ n}}\implies a^{-{ n}}\\\\
-----------------------------\\\\
thus\implies \cfrac{-9t^{25}}{7t^{26}}\implies \cfrac{-9}{1}\cdot \cfrac{t^{25}}{1}\cdot \cfrac{1}{t^{26}}\cdot \cfrac{1}{7}
\\\\\\ \cfrac{-9}{1}\cdot \cfrac{t^{25}}{1}\cdot t^{-26}\cdot \cfrac{1}{7}\implies 
\cfrac{-9}{1}\cdot \cfrac{t^{25}t^{-26}}{1} \cdot \cfrac{1}{7}\implies 
\cfrac{-9}{1}\cdot \cfrac{t^{25-26}}{1} \cdot \cfrac{1}{7}
$

$\bf \cfrac{-9}{1}\cdot \cfrac{t^{-1}}{1} \cdot \cfrac{1}{7}\implies 
\cfrac{-9}{1}\cdot \cfrac{1}{t^{1}} \cdot \cfrac{1}{7}\implies \cfrac{-9}{7t}$

Extra points if right!

Answer:

3/7 bags of flour

Step-by-step explanation:

Things we know:

Carmen uses 2/7 bag of flour to make 1/2 of a batch

To make 1 batch she will use :

2/7 flour/1/2 batch = x flour/1batch

2/7 = 1/2x

1/7 = x

We need 1/7 flour to make 1 batch of cookie

If 1 batch uses 1/7 of the flour then 3 batchs will need:

1/7 flour/1batch = x flour/3 batch

1/7 * 3 = x

3/7 = x

Therefore we need 3/7 flour to make 3 batches of cookies.
