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.

Dude didn't they do the first question simple he made it hard

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

my man sounding like a dollar store chills

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

Im so confused because I'm also using variables within the word problems of percentages! 😫

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

please provide a simpler method for quest 2 if you can

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

So why we are doing that plz any logic to it if something is more ​@@anushagoil7377

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%

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?

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

Thanks.

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???

@hithere8753

3 жыл бұрын

I did the same....

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

what grade is this?

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%)
