Miley mixed ground beef and onions to make a meatloaf. she used all the ground beef from the package label 16oz. she added onions to the meat and had a combined weight of 475 grams. based on the give conversion ratio, how can the ratio that indicates the ounces in 1 gram be calculated

454 : 21 is the ratio of the meat to onions.

Step-by-step explanation:

Given:

Miley used all the ground beef from the package label 16oz.She added onions to the meat and had a combined weight of 475 grams.

Now, based on the given conversion ratio find the ratio that indicates the ounces in 1 gram be calculated:

As, ounces is denoted as oz.

So, to get the ounces in grams we multiply:

16 oz = 454 grams (approximately).

Now, the weight of meat is 454 grams.

And the combined weight is 475 grams.

So to get the weight of onions we subtract weight of meat from combined weight:

The weight of onions =

Thus, the ratio of meat to the onions are:

Therefore, 454 : 21 is the ratio of the meat to onions.

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
