The answer would simplify to 1/6.
47/5=9.40
9*5=45
47/5= 9 2/5
Let the weight if a whole pizza be x grams
Then 1/4 of a pizza weighs x/4 grams and one eighth weighs x / 8. The difference is 32 grams so we can make the following equation:-
x/4 - x/8 = 32
x / 8 = 32
Multiplying both sides by 8:-
x = 8*32 = 256
Answer is 256 grams.

2) 5.625 mg will be left
Explanation:
1) Half-life = 17.5 days
initial amount of Arsenic-74 = 90 mg
To get the equation, we will use the equation of half-life:


2) we need to find the remaining amount of Arsenic-74 after 70 days
t = 70

So after 70 days, 5.625 mg will be left
600 g
Explanation:
Since 1 kilogram =1000 grams
Therefore 3 grams= 3000 grams
Now divide it with 5 partners
3000 divided by 5=600 grams
Each person will get 600 grams of gold dust
