The answer is: -18

That is because, on the number line, they already have 2 numbers. They are -10 to -16. To go from -10 to -16, you subtract 2. Since the mark is the same distance away as -10 to -16 on this number line, you would subtract 2 from -16, which would be -18.

Answer:

-21

Step-by-step explanation:

Each of those lines is -3
If you look at the -10, it goes down 2 lines and goes to -16 meaning that if it only went down one line it would only go to -13

Showing that each line is worth -3

It goes down 2 lines from -16 (-6)

so if you go down 6 from -16 that would get you to -21

Simplify negative 2 and 1 over 9 – negative 4 and 1 over 3.

Ugo [173]

Answer:

The correct answer is

$2\frac{2}{9}$

Step-by-step explanation:

Method 1

We want to simplify,

$-2\frac{1}{9} -(-4\frac{1}{3})$

The double negatives becomes positive,

$=-2\frac{1}{9} +4\frac{1}{3}$

We now add the whole number parts and the fractions separately

$=-2+4-\frac{1}{9} +\frac{1}{3}$

This will give us,

$=2-\frac{1}{9} +\frac{1}{3}$

The least common denominator for the fractional parts is 9.

$=2+\frac{-1+3\times1}{9}$

$=2+\frac{-1+3}{9}$

$=2+\frac{2}{9}$

$=2\frac{2}{9}$

Method 2

We want to simplify,

$-2\frac{1}{9} -(-4\frac{1}{3})$

The double negatives becomes positive,

$=-2\frac{1}{9} +4\frac{1}{3}$

We first convert the mixed numbers to improper fractions to obtain,

$=-\frac{2\times9+1}{9} +\frac{4\times3+1}{3}$

We carry out the multiplication in the numerator to get,

$=-\frac{18+1}{9} +\frac{12+1}{3}$

We add in the numerator to get,

$=-\frac{19}{9} +\frac{13}{3}$

The least common denominator is $9$ .

$=\frac{-19+13\times3}{9}$

$=\frac{-19+39}{9}$

$=\frac{20}{9}$

We convert back to mixed numbers to get,

$=2\frac{2}{9}$

270 is 75% of what number?

Solnce55 [7]

First, you have to divide 270 by 3, so you get 25%. This comes out to be 90. So, 90 is 25%. Now, multiply this by four to get 100%. This comes out to be 360. So, 270 is 75% of 360, which answers the question '270 is 75% of what number?'
