Question 893746: Jonathan raised six goats then entered into a series of business transaction he traded all goats for sheep at an exchange rate of five goats for seven sheep next he exchanged all the sheep for hogs at a rate of four sheep for 2 hogs how many hogs did he get?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! he exchanges all the goats for sheep at the exchange rate of 7 sheep for every 5 goats.
he now has 8.4 sheep because 7/5 * 6 = 8.4.
he exchanges all the sheep for hogs at the exchange rate of 2 hogs for every 4 sheep.
he now has 4.2 hogs because 2/4 * 8.4 = 4.2.
this is not very realistic but that's the way the ratios work.
the overall ratio of hogs to goats would be equal to 7/5 * 2/4 = 14/20 = 7/10 hogs per goat.
if he trades his goats for hogs directly, he will get 7/10 * 6 = 42/10 = 4.2 hogs.
the numbers check out but, once again, they're not very realistic because how do you trade part of a goat or a sheep to get part of a sheep or a hog?
if that was real life, he would have traded 5 of his goats for 7 sheep and then traded 6 of the sheep for 3 hogs.
he would have ended up with 1 goat, 1 sheep, and 3 hogs.
how many hogs is this equivalent to?
let's see.
1 goat is equal to 7/10 of a hog.
1 sheep is equal to 2/4 of a hog.
the equivalent number of hogs would be:
.7 + .5 + 3 = 4.2 hog equivalents.
numbers check out again.
