8 is the answer . Since half a kg is 500g, 100 g would cost 1/5 as much. 1/5 of 40 is 8.

40 % of 12.5 grams = 12.5 * 40/100 grams = 5 grams
$100-$40 dollars
100 ÷ 40 = 2 and a half hours.
You have two-and-a-half hundreds and have 40 for each hundred, so two-and-a-half times 40 is your answer... ...or you could multiply 250 x 40 and divide by 100...
40 (40+40=80)
10 grams... If the half-life is 100 years, that means after 100 years, half the original mass remains. After another 100 years, the mass is halved again. 40/2=20... 20/2=10.
40 % of 12.5 grams = 12.5 * 40/100 grams = 5 grams
In late 2008, bulk potassium was about $ 40 USD per pound.The price for the salt "potassium chloride" was only about 1% of that price, but sharply higher in 2009 (around $ 10 USD per pound in bulk).
I have a German recipe in grams and am bewildered. How much are 40 grams, 500 grams, 50 grams, 100 grams, and 1/4 liter? Thank you

50 percent of anything is half of it. Half of 40 kilograms is 20 kilograms.
200 grams = 0.2 kg cost is .2 x 20 = 4
1000 grams in a kilo therefore 100 grams = 0.1 kilos so 40 g = 0.04 kilos
40 kg = 40 000 grams Answer 40000/400 ballons = 100 ballons
100 grams
After the second half-life of uranium, half of the original amount will remain. Therefore, if you start with 80 grams of uranium, after one half-life you would have 40 grams remaining, and after the second half-life, you would have 20 grams.
