00:00A farmer buys enough feed to last 120 days for the 300 sheep on his farm.
00:05After 30 days, the farmer bought 60 more sheep. How many more days will the remaining feed last for all the sheep?
00:11So, my friends, they're buying enough feed to last 300 sheep for 120 days.
00:17He says 30 days later.
00:18How many days are left after 30 days?
00:20He stays for 90 days.
00:21So that means there's enough feed left for another 90 days, enough to feed 300 sheep for 90 days.
00:32So, how many friends do you have after this?
00:35He was buying from 60 sheep.
00:36Then we call it 360 sheep.
00:40There were 300 sheep.
00:43How many more days?
00:46We'll say enough is enough.
00:47Here's the remaining feed, folks, enough for 300 sheep for 90 days.
00:51How many days will be enough for 360 sheep?
00:54Fewer days wouldn't that be enough?
00:55Then it's an inverse relationship.
00:59As this increases, what should happen, guys?
01:05It needs to decrease.
01:07So, in this case, if it's inverse proportion, I'll say 300 multiplied by 90 equals...
01:12I'm saying x times 360.
01:14If you divide each side into 360s, the 360s become right-hand sides.
01:20X equals.
01:21This part becomes 1, 4, 1, and this part becomes 75.
01:26X equals 75.
01:28So, another 75 days would be enough.
01:31Our answer is that there are plenty of options.
01:33No, that won't work.
