Jenna earns $5 per hour babysitting. last week, she earned a total of $60. the equation 5h = 60 represents the amount of money jenna earned last week. which equation shows the number of hours, h, jenna babysat last week?
a h = 60 × 5
b h = 60 ÷ 5
c h = 60 + 5
d h = 60 − 5

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
