One ounce is equal to 28 grams.
How many ounces are equal to 50 grams?
(round to hundredths)

Work Shown:

(1 ounce)/(28 grams) = (x ounces)/(50 grams)

1/28 = x/50

1*50 = 28*x

50 = 28x

28x = 50

x = 50/28

x = 1.78571428571429 which is approximate

x = 1.79

50 grams is approximately equal to 1.79 ounces

Side note: The true value is closer to 1.7636981 ounces (since that figure of 28 grams should be more about 28.3495231); however, we'll stick to the numbers your teacher gave you.

idk

i hope i

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
