Answer
28 ounces = 793.79 grams
28 ounces = 0.79 kilograms.
Step by step explanation
1 ounce = 28.3495 grams
Now let's convert 28 into grams.
Here we have to multiply 28 by 28.3495
28 x 28.3495 = 793.787 grams
Now let's convert 793.787 into kilograms
1 kilograms = 1000 grams
793.787 grams = 0.79 kilograms
10.3 = 0.6y...divide both sides by 0.6
10.3 / 0.6 = y
17.17 = y <=
I suppose you want to know such number. Since we have a two digit number consisting of two consecutive integers, the only possible numbers are:

Since we sorted all the cases out, we simply have to check which one satisfies the requirement. For each number, we'll write four times the the sum of its digits, and add 6, hoping to get the original number.



So, the answer is 34.
