Maya wrote the expression 3+5+4.5 to represent the total distance that she traveled. which statement best describes maya’s expression? maya’s expression will generate the correct sum because of the associative property. maya’s expression will generate the correct sum because of the commutative property. maya’s expression will generate the wrong sum because she violated the associative property. maya’s expression will generate the wrong sum because she violated the commutative property

The statement, Maya’s expression will generate the correct sum because of the associative property will describe the best.

Solution:

Maya’s expression will generate the correct sum because of the associative property.

Maya wrote the expression

As per commutative property of addition if we change the order still the sum will be same, which means

Here also,

Again

As both the results are same, hence this is meeting the commutative property of addition.

the answer will be

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
