Answer:

\frac{(3-2a)}{a^2}

Step-by-step explanation:

Given expression is,

\frac{3}{a^2}- \frac{2}{a}

First equalize the denominators of the fractions,

\frac{3}{a^2}-\frac{2a}{a^2}

Now combine the fraction as a single fraction,

\frac{(3-2a)}{a^2}

Since, we can not solve this fraction further, this will be simplified form of the given expression.

Which expression gives the best estimate of 45 percent of 76?
jonny [76]

Answer:

<h2>1/2 of 80</h2>

Step-by-step explanation:

45% is close to 1/2 (50%) and 76 is close to 80, so 1/2 of 80 is the best answer.

1/2 of 80 is 40

45% of 76 is 76 x 0.45 is 34.2
