Consider the division expression 7 1/2 divided by 2. Select all multiplication equations that correspond to this division expression. 2 * ? = 7 1/2 7 1/2 * ? = 2 2 * 7 1/2 = ? ? * 7 1/2 = 2 ? * 2 = 7 1/2 I need help with this question

2 * ? =

OR

? * 2 =

Step-by-step explanation:

The given expression is:

divided by 2.

The given expression a mixed fraction.

Let the result of the expression be equal to .

Therefore, the expression can be written as:

...... (1)

Multiplying equation (1) by 2:

OR

Alternatively, this expression can be written as:

2 * ? =

OR

? * 2 =

Therefore, the following multiplication equations corresponding to equation (1) are:

2 * ? =

OR

? * 2 =

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1

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
