First, convert the kilograms to grams. One kilogram is 1000 grams. So multiply it by 1000. Then subtract 2305 from 4000. 4000-2305=1695. So 1695 grams were taken out.
784/ 93 = 8.43010752688
93 * <span>8.43010752688 = 784</span>
A, because you follow the numbers and just put "is to" and "as" in the middle.
