Chelsea needs a combination of 32 small, medium
and large beads to make a bracelet. On Tuesday
she uses 114 large beads, 50 medium beads and
28 small beads. Which equation and solution
model the number of bracelets, b, she is able to
make on Tuesday?

the correct answer is 5 6 and 7

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

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
