Let the total sales equal x. The sales in New England are $${\frac{{\mathtt{1}}}{{\mathtt{9}}}}{\mathtt{\,\times\,}}{\mathtt{x}}$$. Set this equation equal to the amount made in New England, and solve.

$${\mathtt{600\,000}} = {\frac{{\mathtt{1}}}{{\mathtt{9}}}}{\mathtt{\,\times\,}}{\mathtt{x}}$$     Multiply by 9

x = $5,400,000

To solve this, you must use logarithms.

x = $${{log}}_{{\frac{{\mathtt{1}}}{{\mathtt{2}}}}}{\left({\mathtt{32}}\right)}$$

x = -5

2.54 * 10^-1

Dividing by fraction is the same as multiplying by the reciprocal of that fraction. So it would be the same as 5 * 3/2.

5/1 * 3/2 = 15/2

The first answer is incorrect. You do not divide to find percentages. You multiply the number by the percentage in decimal form. 5% in decimal is .05.

So do 3600 * .05 = 180

8n + 3 = 5

Subtract 3 to get n alone

8n = 2

Now divide by n to get the answer.

n = 1/4

A power to a power is the same as multiplying the two powers. So 10^10^50 is the same as 10^500, which is 10 with 500 zeros after it. That's it :)

You can just add them together with this site: 129211732691

x + 1800 - 2700 = 800

Solve for x: First combine the 2 numbers on the left

x - 900 = 800

Now add 900 to the right to get x

x = 800 + 900

x = 1700

Could you give more information on the problem you're doing this with?

But the easiest way: If you have the exact answer, and the estimate is lower than that answer, it's an underestimate. If it's higher, then it's an overestimate.
