79% is the same as 0.79

So just multiply 0.79 and 12

= 9.48

Hi Melody,

Sure, sorry about that

They asked: "What is the opposite of the square root called?" ("cuandrada" is supposed to be spelled "cuadrada")

I said:

It is called the square of the number.

The opposite of $${\sqrt{{\mathtt{x}}}}$$    is x²

So...

A Toyota.

Se llama el cuadrado del número.

El contrario de $${\sqrt{{\mathtt{x}}}}$$    es x²

So 5⁸/ 5² is the same as 5^(8-2)

= 5⁶

Set up a proportion:

(1/3) cups over 6 servings = x cups over 20 servings. $${\frac{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}{{\mathtt{6}}}} = {\frac{{\mathtt{x}}}{{\mathtt{20}}}}$$

Then, cross multiply:

$$\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{20}} = {\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{x}}$$

Multiply it out:

(20/3) = 6x

Divide both sides by 6. Dividing by 6 is the same as multiplying by (1/6)

 x = (20/3) * (1/6)

x = 20/18

Simplify. 

x = 10/9 or 1.11111111...cups.

Do you mean 9 times the square root of 3?

If that's the case, just put in:

9* sqrt(3)

The calculator on this website also has buttons for inputting roots and powers of numbers. Just click/type in the number, then click the button:) 

True, because:

66 2/3% of a number is the same as 2/3 of it, so

A  66 2/3% decrease of the number (say, x) would be:

1x - (2/3 * x) 

Which would equal: 

1/3x

Therefore, one third of a number is a 66 2/3% decrease of a number.

No lo necesitas. Escriba los fracciones o usa los paréntesis:)

30 divided by -3/4

When a number is divided by a fraction, you multiply it by the fraction's reciprocal (flip the numerator and denominator).

So 30/ (-3/4)

= 30 * (-4/3)

Multiply the numerators and denominators.

= (30*-4) / (1*3)

= -120/3

Simplify.

= -40

Another way would be to write -3/4 as the decimal -0.75

Then, divide 30 by -0.75

= -40
