You know what, this was my first video of Khan Academy and it made a bad impression, answering questions difficultly

[candyxoxo]

Khan, normally I get your lectures but this one is too difficult to get😞

[nemonemo]

Perfect, especially the last example. Make sense and most common in real life. Cheers

[brendadancy-clegg]

Just complicated but as I listened and seen it being worked I can see, but not ready for this yet.

For the first question, Turn 30 percent into a decimal. This will be 0.3. Now, Multiply 0.3 by 1060, which gives us 318. Finally, subtract 1060-318=742.

He splits up 100 and 100 to make them 100% each and then adds 20% to one side which is odd because it technically equals 120% for the goblins if kept apart. While yes, technically speaking it is 20% more than the other side, the way he wrote the question you would think 220 is 100% and split it 60/40 which is 20 percent more for one side (132/88). I believe this is the more accurate method to calculate the problem and the way most people would do it if asked because you would be calculating the total sum to 100%, not 120%.

The ratio if done his way becomes 55% and 45% because he added %20 more of something to the total, diluting the initial value he started with, making the difference now only 10% and not 20%

please provide a simpler method for quest 2 if you can

me: i understand

My answer on the last problem is 148.5 because 10% of 165 is 16.5cm so I subtracted the 10% to his height

This is a good advantage for learners like me but why's someone disliking videos
this is some good help for us

100%=220
20%=?

20*220/100=44
20%=44.(Extra Goblins)
50% of 220= 110.
50%+20%=70%.
110+44= 154 goblins.

(154/220*100=70%)

at 3:45 when you were figuring out the answer on how meany goblins there are, where did you get the 1.2 from?

[ZaBaoi]

thx a lot I have a bloody nose and I had a very rough time doing this subject.

[meriemghandir]

Isn’t the last question 148.5 I’m so confused

[etracseez]

In the second problem I set it up as a 40% Wizards / 60% Goblins ratio (because the difference between 40% and 60% would be 20% and 40%+60%=100%) However when solving for 60% from 220 (100% )I got a different answer???

[chickendotz]

there needs to be an easier way to do this.

[FabstaPizza]

at 3:41 Sal suddenly made the wizards or W a 1? How does that make sense when it shouldnt have a number as we dont know what number it is u cant just make any letter a number, also at 4:19 he made the W AGAIN a 1, how does this make any sense!? Can someone PLEASE help me?

[MiLadyBugaboo]

In the second way of writing it, I thought you had to use X over the 1060 and then cross multiply??

[harvardman]

Actually, I found another solution: If 30% of 1060 is 318, then 1060-318=742
