66 2/3% = _____.

Answers

66 2/3% means (66 2/3)/100
as we knw%=100 so replace it by 100
{[(66*3)+2]/3}/100

= (200/3)/100
= (200/3)*(1/100)
= 2/3 so its the simplest form
hope it helps

What is 5.2E11 in scientific notation

Answers

5.2E11 is the equivalent of scientific notation when you use a calculator.

5.2 x 10¹¹ is its written form.

5.2 is the coefficient.
10 is the base
11 is the exponent

5.2 x 10¹¹ in standard form is 520,000,000,000

You're going to multiply by a factor of 11 or move the decimal place 11 places over to the right. Your answer is 520,000,000,000 or 520 billion.

Translate the statement into an equation. Then solve the equation. The sum of 8 and 3 times a number is 23.

Answers

The best way to solve this is to write it out part by part.

The first part is "the sum of 8 and 3," which is (8+3)

The second part is "...times a number," so we have n(8+3)

Lastly, "...is 23," means n(8+3) = 23, so here's the equation. In order to solve for n, divide both sides by (8+3) so 23/(8+3) which is 23/11. So the "number" is 23/11.

Let the number be x
8+3x=23
3x=23-8
3x=15
x=5
The number is 5
