Lucy has 4 inches of ribbon that she wants to cut into 6 equal-sized pieces. What is true about the length of each piece of the ribbon?

4 inches/ 6 = 0.67 inches

each piece of ribbon is 0.67 inches or 2/3 of an inch in length

Step-by-step explanation:

Each piece has 1/6 of 4 inches of ribbon.

Step-by-step explanation:

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
