Which of the following would represent the first step in simplifying the problem 7 divided by 5 (6—2) divided by 2 ? • 7+30–2 Divide 2
•7+5(4) Divide 2
•12(6–2) divide 2
•7+5 (6) –1
•
•

7+5(4) divided by 2

Step-by-step explanation:

this is what i would do because of BEDMAS

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
