If tina had 4.6 gallons of water in one bucket and 2.3 gallons in another bucket, how many gallons did she have all together?

Hey!

Since it says "all together", that means you have to add both amounts.

In one bucket, she had 4.6 gallons, and in another, she had 2.3 gallons. Add 4.6 and 2.3

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
