The change that happened from the first half of the equation to the second half was you moved the 9 and the 4c around.
Commutative property of addition allows you to do that. It's what says that 2+3 is the same thing as 3+2

B.

Commutative, root word is commute- to move around. a+b+c = c+a+b
Associative deals with group (a+b)+c = (a+c)+b.
Both of these pertain to only addition and multiplication.

Distributive means to distribute the number outside of the parentheses to the numbers inside by multiplication or division. Only if the numbers inside are being added or subtracted

Inverse- Additive- equals zero. 2+(-2)=0
Multiplicative- equals one. 9 * (1/9)=1

11. The table shows the lengths of fish caught by three,

blsea [12.9K]

Numbers can be ordered in ascending or descending order.

The length of fishes from greatest to least is

$Emily = 12 \frac 34$ .
$Emma = 12.7$ .
$Anne = 12 \frac 35$

Given

$Emma = 12.7$

$Anne = 12 \frac 35$

$Emily = 12 \frac 34$

Convert all fractions to decimals

$Emma = 12.7$

$Anne = 12.6$

$Emily = 12.75$

Arrange from greatest to least

$Emily = 12.75$

$Emma = 12.7$

$Anne = 12.6$

<em>Hence, the length of fishes from greatest to least is </em>

$Emily = 12 \frac 34$ $Emma = 12.7$ $Anne = 12 \frac 35$
